Mars is the engine of the birth chart: the planet of drive, desire and action. It governs how you go after what you want, how you stand your ground, your physical and sexual energy, your courage and your anger. Named for the Roman god of war, it is raw will made into motion. This is a complete guide to Mars in astrology: what it means, how it moves through every zodiac sign and house, what Mars retrograde brings, its tarot and crystals, and how to find your Mars sign. Read it as a portrait to recognise yourself in, never a rule to live by.

What Mars Represents
In astrology, the planets have a meaning different from the astronomical understanding of what a planet is. Mars is the planet of will and want: assertion, ambition, courage, anger and desire, the force that makes you act.
"Raw desire is directed by Mars, and that includes everything from our sex drive to our professional pursuits."The AstroTwins, Astrostyle
Two things shape how your Mars expresses: the sign it sits in (your style of action) and the house it sits in (where you put your energy). Here is Mars through both.

Mars Retrograde
About every two years, Mars appears to slow and move backward for roughly two to three months, a rarer retrograde than Mercury's. Astrologers read it as a time to review your drive: how you assert yourself, how you handle anger, where you push too hard or not hard enough. Energy can feel frustrating or stop-start, so it is a season to rethink and recharge rather than charge ahead. A reflective reading can help you channel the heat: see our Mars retrograde tarot spread.
Mars in Tarot and Crystals
In the Hermetic tarot of the Golden Dawn, Mars's Major Arcana card is The Tower (XVI): sudden force, breakthrough and the lightning bolt that clears the ground, all the raw, disruptive power Mars can bring. You can read more in our guide to the Major Arcana.
In crystal lore Mars is linked to iron and to bold red stones. Carnelian carries its courage and drive, while red jasper and garnet echo its strength and passion. These are traditional associations rather than proven properties. Our guides to crystals for every zodiac sign and star sign crystals pair a stone with each sign and its ruling planet.
How to Find Your Mars Sign
Mars takes about two years to circle the zodiac, so it can sit in any sign in your chart. Our free birth chart calculator reveals your exact Mars sign, the house it falls in, and every other planet. From there, your houses and the rest of the planets complete the picture.
Is Astrology Real?
Honestly, astrology is a language of symbols and meaning rather than a science of cause and effect. Mars cannot make you angry or brave. What a placement can do is hold up a mirror, offering words for the way you already act and desire, and a gentle prompt to reflect. Read it as a story about yourself, take what rings true, and leave the rest. When you are ready to go deeper, begin with zodiac and astrology and map your own birth chart.
