Natal Mercury in Leo

When a person has his natal Mercury in Leo, the sign will grant a big part of its attributes to everything that Mercury represents in his chart. As Mercury is generally governing our intellect and communication, Leo energy will make the native’s expression quite vivid and even theatrical. It will also aid him leadership abilities, as it makes the chart owner eager to be listened to and admired by other people.

Leo is the fifth sign of the zodiac, and has the Sun as its ruling celestial body. Leo is also the natural ruler of the fifth house, which rules fun and recreation, children, love and all that is connected with entertainment. This makes Leo Mercury people concentrate a lot on whatever is fun and involves the intellect. They will like playing games, and will also easily be drawn towards gambling. More precisely, they will prefer games that are not based on luck, rather on knowledge and strategy, even when gambling. Leo is one of the signs mostly connected with our Ego, the solar King of the zodiac, and as a result, a Mercury placed in this sign will give strong boosts to the native’s self-confidence.

In the sign of Leo, Mercury is in peregrine condition. Peregrine is a rather neutral condition, where a celestial body does not function very potently (as it does when in domicile or in exaltation), nor is very weak (as it does when in detriment or fall). Yet, we should mention that the rather hot and active traits of Leo make Mercury operate in a quite extroversive pattern. Mercury placed here can operate out of control, which on the one hand can enhance the native’s communicative abilities, on the other hand, can easily lead him to Hybris. The reason is simple: pride and arrogance, a typical effect that Leo can have on whatever it touches. Thus, people who have this natal placement should be very careful to not misuse their Mercury, and try to balance out the natural narrow-mindedness which such Mercury in Leo can give. More information about Mercury’s potency in the signs can be read in the article about Mercury’s Essential Dignities.

We should note that Mercury needs less than a month to move to a next sign, and is the quickest moving planet, as it is located very close to the Sun. Also, it cannot be more than one sign away from the sign where the natal Sun resides, and has three times per year a period of retrograde motion, where it moves backwards for apparently 20 days in the natal chart. Mercury is impersonated by the ancient Greek god Hermes, who was the messenger of the gods and protector of commerce. The planet governs intellect and trade, data and communication, while also transportation. In addition, the darker traits of Mercury include rulership of lies, swindling and theft, which are also definitely an archetypical part of commerce. Mercury is a hermaphrodite planet, with a balance between its masculine and feminine side. For this reason, it is rather well-received in most signs, as it can adapt quite easily to any possible surroundings.

Mercury in Leo makes one’s speech theatrical. He will use a lot of gesticulation, and has the power to change the tone of his voice in such a way that the messages are transmitted to the audience exactly how he wants to. It is not a surprise that this is an amazing aspect to have if someone is a performer, an actor, a singer or in other occupation connected with speaking to masses. This aspect can also be perfect for salesmen, politicians, and of course swindlers of all types. Acting is closely connected to lying as an archetype, because the person speaks out differently than what he thinks, the person performs a role different than what he really is. In addition, we already mentioned that Mercury is the God protector of conmen in the ancient mythology. As a result, an individual born under such a natal placement may excel in all these fields, for better or for worse. If you have Mercury in Leo, do not forget to always question your morals. If someone you know has this aspect, do not rush to call him a liar – this might be a predisposition yet will not always get activated. Yet, such people for sure will play out the fisherman’s story, magnifying their successes and generally bragging about themselves.

Leo Mercury people are very confident concerning their ideas, and of course, always think they are right. In case that their opinion is challenged, they will easily get into a dispute even when they sense that they are wrong. Such people will easily try to influence others and impose their way of thought. They adore seeing other people being convinced and will feel great pride when reaching success in doing it. They usually have an opinion on everything, and will frequently offer their advice even if it is not requested. Psychologically, all this is of course connected with the Leo need to be in the center of attention. On the other hand, the directness of a Leo Mercury may indeed become motivating to other people. Thus, chart owners with this placement have a duty: to help their knowledge, intellect and wisdom blossom, in order to be able to give good advice to people who actually are weaker and who yearn for it. Of course, control is needed to not press others, and such a chart owner should always search inside him to discriminate whether his actions are of good will or just an inner need for boosting his own ego. Watch out to not fall into the trap of feeling powerful over other people thanks to the intellect.

A very positive trait that a natal Mercury in Leo gives, is natural positivity and optimism. The speech of such individuals usually contains a lot of humor and creates a happy atmosphere both for them and their audiences. They give a performance in front of their friends and adore seeing happiness on their faces as a sign of appreciation or even admiration. This placement is definitely good for stand-up comedians, while also all other types of animators. The native’s mind can easily create imaginative stories, or take a real one and divert it in order to make it sound more interesting. Such people are natural storytellers, and so they should be careful to not use this wonderful and magical ability in such ways that they distort important parts of reality. Their stories are great when not taken seriously, yet on the other hand, could create trouble for other people that easily believe them.

Another thing that people with Mercury in Leo should be a little bit careful about is their natural attraction to drama. When they are facing some difficulties, they might become drama queens, which of course is better to avoid. If you have this placement, try to observe yourself and your reactions, especially in critical situations. In addition, a bit more control over anger is sometimes necessary, as Leo Mercury may make verbal reactions quick and may prompt such people to speak in ways that they would not when calm. On the other hand, it is a delight to see people with such a placement being happy. His dramatic traits may create a wonderful performance for the eyes of other people, and we can definitely say that these people know how to celebrate their successes and all the good events of their lives.

As we already mentioned, Mercury in Leo is connected with joy and children. This natal placement will have, as an effect, being a funny parent for a child, or generally enjoying playing with children. Children always have a tendency to admire and copy older people that are role models, and a Leo Mercury person is a shiny object for their young eyes. This makes such natives excellent sports coaches, kindergarten teachers, or even just the funny uncle whom the nephews adore playing with. Again, if you are in such situations, always be careful to indeed pass correct archetypes to children, and not do your performances just in order to feel admired. The children will copy anything you present, so consciously choose what you have to offer them.
Natives with Mercury in Leo can also be particularly good in gambling. You guessed right, there is no better natal placement for having a poker face. The whole game becomes an artistic performance of fooling the opponents, which brings a lot of joy. Of course, such people are very antagonistic and will always strive to win and not only to play.

The fiery energies of Leo can make such individuals inflexible concerning their ideas and opinions. When someone has a different one, they might feel an urge to proselytize him and change his thought. Leo is a rather extrovert sign, not seeking for harmony but for dominance and conquest. By changing the views of other people, individuals with Mercury in Leo feel that they expand their own territory. When someone resists fiercely and has a radically different opinion, mechanisms of attack can get triggered, making the native quarrel and even raise his tone. If a Leo Mercury is hurt by words, they will keep grudges. They will not admit defeat, and will eagerly wait for the time to take an intellectual revenge on the person that made them feel not being the authority.

When a woman has this placement in her natal chart, her mind tends to operate as a man’s one. She may have been passing a lot of time with boys in his young years, maybe even male members of the family such as brothers and cousins. Thus, she has developed a masculine way of thought, making her mind more active and less emotional. We should note here, that this has nothing to do with her sexual orientation; it is just patterns of emotional responses towards receiving information through communication. Such women will be the heart of the company.

When a Leo Mercury is well aspected in a natal chart, the native can indeed excel in the life area that the sign of Leo rules. Find out which house cusp falls in the sign of Leo, to understand better where this will manifest. Good aspects to natal Mercury in Leo signify a healthy approach to communications, without any real problems created by the egotistical tendencies. Still, adverse aspects of malefic planets can indeed create some issues. Mars is mostly responsible for aggressive speech while also excessive lying, while Uranus for unpredictable behaviors and other types of mental/neural complications. Pluto can also be quite challenging when in a difficult aspect, as he may bring a lot of cunning thoughts and awaken manipulative techniques. In case you have difficult aspects to your Leo Mercury, try to find long-term ways of diminishing your ego. Speak less about yourself, and dedicate time to what other people have to say. Ego dissolution through meditation can prove life-changing, as you will understand better the mechanism behind your existence afterwards and then will be able to use it for the good of others, and not only for your own self.

As usual, there is so much hatred for Leo. It is the sole reason I hate reading about my zodiac sign because most so called astrologers never mention Leo’s good attributes (Leos are very giving and fair and fight for the underdog) or anything that deviates from the stereotypical or the norm (Many Leos, especially August Leos, are actually very shy and are uncomfortable with large amounts of attention. Leos don’t do things to draw attention to themselves; they are naturally magnetic). You astrologers never give Leo a break. Your “Sun in Leo” description was just as bad as this one, and I don’t see any other descriptions that have as much negativity as Leo’s. Leos are very honest, up front people, so why you felt the need to pin lying on “mercury in Leo” is beyond me. While all signs are capable of lying, Air and Water sign mercurys are much more prone to lying. Leos seem to get a bad rap from most astrologers, but particularly from Virgo astrologers (those with heavy Virgo placements) and Scorpios. Though, I’ll admit that Pisces astrologers tend to be less bias and have a deeper understanding of Leos (they have a deeper understanding of most things) than other astrologers, who regurgitate the same unoriginal, over generalized, over simplified, distorted B.S.


I agree with most of what was said.. Even the lying part. However, this is a skill in me that is never used, because uranus and Saturn both trine my mercury in my natal chart. Moreover I think another layer to this topic that is under appreciated is the house placement and HOW it’s aspected by other planets. I have mercury in Leo in the 3rd house, in square aspect to Jupiter in Gemini in 12th house. And I believe my 2nd house Leo moon in sextile aspect with Jupiter, intensifies my mercury traits.


I agree with you to some extent, but not about the ”hatred”part. Nobody hates Leo, on the contrary, Leos are usually the most admired people. The article is about Mercury and how it acts in the sign of Leo, not about Leos in general. Virgo and Capricorn have a tendency to hate everybody and everything, including themselves, so it is not surprising that they envy Leo, rather than hate them. Most astrologers are fair enough and they have to point out not only the attractive traits of a sign or placement, but also the challenging ones.


I was also really confused about the lying
. my Sun, Mercury and Venus are all in Leo
.. I am a pretty bad liar. I also do not seek attention.. I just want to voice what needs to be voiced.. I also notice a trend with Virgos and Scorpios hating on Leos. Pisces love us, as do Aquarians.


I agree, Jenni. I have Sun, Mercury and Ascendant in Leo, and I cannot relate to most of the typical Leo descriptions. Yes, Pisces and Aquariuses do love us, and I love Pisces and Aquariuses as well. They are the last two signs of the zodiac and I think they are more mature, more spiritual and on a “higher plane” than the other signs, in a sense. Aquarius represents the wise, old sage who has lived many years and has gained much wisdom, and Pisces is like pure spirit, the “in between”, after we have died and before we are born.


Great article!
