Aquarius is most compatible with Gemini and Libra, the other air signs, who love ideas, conversation and independence as much as Aquarius does. Sagittarius and Aries, fire signs a friendly angle away, are close behind, since both give Aquarius plenty of room and plenty to talk about. Leo, the sign directly opposite, is the most magnetic match and the one with the most to learn from Aquarius. The harder fits are Taurus and Scorpio, which want a kind of closeness Aquarius takes longer to offer.
Aquarius tends to choose partners the way it chooses friends, and often the partner was a friend first. That's the thread running through every pairing below.
Friendship first: how Aquarius chooses a partner
Aquarius (roughly January 20 to February 18, with the boundary moving by a day in some years) is fixed air. Air is the element of thought and connection, and fixed signs hold their ground. Aquarius has two rulers: Saturn in traditional astrology, linked with principle and structure, and Uranus in modern astrology, linked with independence, originality and sudden change.
The result is a sign that is friendly with everyone, loyal to its values, and wary of anything that feels like being owned. Aquarius often falls for someone it has argued happily with for months: the person from the book club, the colleague who shares its strange sense of humor, the friend who never needed it to be anyone else. It wants a partner with a life of their own, a mind worth arguing with, and enough trust that time apart doesn't become a crisis. It struggles with possessiveness, emotional demands that arrive without explanation, and partners who need constant reassurance. Our guide to the Aquarius woman in a relationship shows what this looks like day to day, and most of it holds for any Aquarius.
The air signs: Gemini and Libra
These sit four signs from Aquarius in a trine, the most harmonious angle.
Gemini and Aquarius is a match of minds. Gemini, ruled by Mercury, is quick and curious, and it keeps Aquarius entertained. Both love unusual people and new ideas, and neither crowds the other. The weak spot is feelings: two people who are comfortable thinking can put off saying what they feel for a very long time.
Libra and Aquarius shares a sense of fairness. Libra, ruled by Venus, brings warmth, charm and a love of partnership, and it softens Aquarius's cooler edges. Aquarius brings conviction and originality that Libra admires. The friction is that Libra wants romance and togetherness, and Aquarius sometimes forgets the romance part. Remembering the anniversary goes a long way.
Sagittarius and Aries: the independent fire signs
Fire and air sit two signs apart in a sextile. Both of these fire signs share Aquarius's appetite for freedom.
Sagittarius and Aquarius may be the most independent couple in the zodiac. Sagittarius, ruled by Jupiter, loves adventure, honesty and big ideas, which suits Aquarius perfectly. They can travel separately and meet in the middle, quite happily. What can get lost is emotional check-ins, because neither naturally asks.
With Aries, ruled by Mars, Aquarius gets energy and directness. Aries pushes Aquarius to act on its ideas rather than just discuss them. Aries can find Aquarius too detached in an argument, and Aquarius can find Aries too heated. Both like their own space, which makes them easy to live with.
Leo across the wheel
Leo and Aquarius sit opposite each other, and the pull is strong. Leo, ruled by the Sun, is warm, personal and generous, and it loves to be adored by the people closest to it. Aquarius is friendly to everyone and possessive of no one, focused on the group and the principle. Each has what the other lacks.
Both are fixed signs, so both are stubborn. Leo can read Aquarius's calm as indifference, and Aquarius can find Leo's need for attention a bit much. When it works, Leo teaches Aquarius to make someone feel special, and Aquarius teaches Leo that love doesn't need an audience. It's often a striking, loyal partnership.
Neighbors with history: Capricorn and Pisces
Aquarius's neighbors on the wheel share something with it, which makes them more interesting than their position suggests.
Capricorn shares Saturn, Aquarius's traditional ruler. Both are principled, serious about their work and slow to show emotion. Capricorn values tradition and Aquarius values change, so they can disagree about how things should be done. They rarely disagree about whether they should be done well.
Pisces is the sign after Aquarius. Both are idealistic, accepting and drawn to causes larger than themselves. The difference is that Aquarius meets the world through the mind and Pisces through the heart. Pisces may feel lonely when Aquarius goes into its head; Aquarius may feel crowded when Pisces wants to merge.
The harder matches, in brief
Taurus and Scorpio are the two fixed signs that square Aquarius, and they are traditionally its most challenging matches: Taurus wants routine and Aquarius wants reinvention, while Scorpio wants emotional depth and Aquarius wants room to breathe. Cancer and Virgo sit at an awkward angle that makes daily rhythms hard to sync. We go through all four, and what helps, in signs least compatible with Aquarius.
Two Aquarians give each other plenty of space and plenty to talk about. The danger is giving each other so much space that nobody brings up feelings at all.
Looking past the Sun sign
An Aquarius with the Moon in Cancer may want far more closeness than the stereotype, and one with Venus in Pisces may be deeply romantic. A free birth chart shows your Moon and Venus signs, which say much more about love style than a Sun sign alone. And if you're wondering whether a particular Aquarius is interested, our piece on signs an Aquarius man likes you covers the quiet signals. The clearest one, as always, is someone who keeps making time for you.

Who should an Aquarius marry?
Libra, Gemini and Sagittarius are often suggested for long-term partnership, as they respect Aquarius's independence. Leo can be a magnetic and loyal spouse when both value each other's style of love.
Are Aquarius and Aquarius compatible?
