Let’s face it — when it comes to relationships, trust is everything. But what if the stars have something to say about someone’s faithfulness? While astrology isn’t an exact science, many people swear by zodiac signs to explain compatibility, personality traits, and yes — even infidelity. So, which zodiac signs are most likely to stray in a relationship?
Before we dive into the rankings, a quick disclaimer: not every person born under a certain sign is doomed to cheat. Life is complicated, and people are more than just their star signs. Still, astrology offers some fun (and maybe eerily accurate) insight into our tendencies — both good and bad.
So let’s rank the 12 zodiac signs from the most faithful to the most likely to cheat, based on their general characteristics in love and relationships.
12. Capricorn (December 22 – January 19)
Most Faithful
Capricorn takes the crown as the most faithful sign in the zodiac. These grounded, goal-oriented people are all about loyalty, commitment, and building a stable life with someone. They don’t play games, and they’re not interested in fleeting flings. Once they’ve committed to a relationship, they’re in it for the long haul — no exceptions.
Capricorns approach love like a business deal: they weigh the risks, think long-term, and once they invest, they’re not pulling out unless absolutely necessary. If you’re looking for a dependable partner, Capricorn is a safe bet.
Cheating Potential: 2/10
11. Cancer (June 21 – July 22)
Cancers are emotional, nurturing, and fiercely loyal once they’ve opened up. Ruled by the moon, they crave deep emotional connection and tend to wear their hearts on their sleeves. When they fall in love, it’s wholehearted and genuine.
Cheating just doesn’t align with Cancer’s values. The guilt would eat them alive, and they’d rather fix a relationship than seek comfort in someone else’s arms.
Cheating Potential: 3/10
10. Taurus (April 20 – May 20)
Taurus is ruled by Venus, the planet of love and beauty, but don’t mistake that for promiscuity. Taurus craves security and routine — and cheating? That’s messy and unpredictable.
Once they’re emotionally attached, Taurus is incredibly loyal. They’re not likely to risk a good thing for a temporary thrill. However, if they feel constantly unappreciated or taken for granted, their darker side can emerge — though they’d likely end the relationship before straying.
Cheating Potential: 3.5/10
9. Virgo (August 23 – September 22)
Virgos are analytical, practical, and often perfectionists — and that extends into their relationships. They don’t jump into love easily, but when they do, they’re all in. Cheating doesn’t really make sense to a Virgo. They’re planners, not impulsive types.
That said, Virgos can sometimes overthink things or become distant if they’re dissatisfied. But instead of cheating, they’re more likely to withdraw emotionally or leave the relationship altogether.
Cheating Potential: 4/10
8. Leo (July 23 – August 22)
Leos are loyal — when they’re in love. They thrive on admiration and being the center of attention, which can be a double-edged sword. When they feel loved and respected, they’re incredible partners. But if they’re ignored or undervalued, they may seek validation elsewhere.
A Leo with a strong sense of self-worth and a secure relationship is unlikely to cheat. But a Leo who feels neglected? That’s where things can get messy.
Cheating Potential: 5/10
7. Scorpio (October 23 – November 21)
Scorpio’s reputation precedes them — passionate, secretive, and intense. When they love, they love hard. But when trust is broken or they feel betrayed, their sting can hurt. Scorpios can be deeply loyal, but their emotions run deep and sometimes erratic.
They’re capable of cheating, especially if they suspect their partner of doing the same. Revenge cheating? Absolutely. Random cheating? Not so much. Scorpios are more likely to cheat as a form of emotional retaliation than pure lust.
Cheating Potential: 6/10
6. Pisces (February 19 – March 20)
Ah, Pisces — the dreamy romantic. They fall hard and fast, and sometimes, that’s the problem. Pisces can confuse infatuation with love and often live in a fantasy world. If their current relationship doesn’t live up to their dream version, they might seek out someone else who does.
They’re not typically malicious or calculating — they just get swept up in emotion and connection. Unfortunately, that means cheating can sometimes happen without fully thinking it through.
Cheating Potential: 6.5/10
5. Libra (September 23 – October 22)
Libras love love. They thrive on connection, charm, and partnership. The problem? They also hate confrontation and can be a bit indecisive. If things aren’t going well in their current relationship, they might not break up — they might just find someone else to fill the emotional void.
Their need to be adored and their flirtatious nature can sometimes get the best of them, especially when they’re feeling emotionally neglected or unbalanced.
Cheating Potential: 7/10
4. Aries (March 21 – April 19)
Aries is passionate, impulsive, and driven by desire. They crave excitement, and if the spark dies in a relationship, they might go looking for it elsewhere. It’s not that they’re heartless — they’re just wired for adventure and action, and sometimes monogamy can feel a little too… still.
If Aries cheats, it’s likely a spur-of-the-moment thing rather than a premeditated affair. They may regret it instantly — but that doesn’t change the damage done.
Cheating Potential: 7.5/10
3. Aquarius (January 20 – February 18)
Aquarius is a bit of a wild card. They’re fiercely independent and don’t always play by traditional relationship rules. While not inherently unfaithful, they do tend to detach emotionally, which can lead to blurry boundaries and rationalizations.
They might justify cheating as a way to explore a connection or a “lesson” in love — not because they’re heartless, but because they prioritize freedom and new experiences over convention.
Cheating Potential: 8/10
2. Gemini (May 21 – June 20)
Gemini’s dual nature often gets them a bad rap in relationships — and for good reason. Ruled by Mercury, the planet of communication and curiosity, Geminis are always seeking stimulation. If their relationship starts to feel routine or boring, they might go hunting for something (or someone) more exciting.
They don’t always set out to cheat — sometimes they just “accidentally” slide into someone else’s DMs. Their flirty, spontaneous energy makes them charming — and, unfortunately, hard to pin down.
Cheating Potential: 9/10
1. Sagittarius (November 22 – December 21)
Most Unfaithful
And here it is — the sign most likely to cheat: Sagittarius.
This free-spirited fire sign is ruled by Jupiter, the planet of expansion and freedom. Sagittarians crave adventure, exploration, and new experiences. That applies to love, too. They can be wildly passionate and fun partners — but they hate feeling caged in.
Commitment can feel like a trap to Sagittarius, and if they’re not fully invested or feel stifled, they may look for excitement elsewhere. It’s not always emotional cheating — sometimes it’s purely physical, driven by curiosity or boredom.
They don’t mean to hurt people — but their need for independence often outweighs their need for consistency.
Cheating Potential: 10/10
Final Thoughts
Remember, your zodiac sign doesn’t define your destiny. There are faithful Geminis and wandering Capricorns — people are complex. But astrology can offer a fun (and sometimes eerily accurate) lens into relationship behavior. Whether you’re just curious or side-eyeing your partner’s birth chart, take it all with a grain of stardust.
Still… if you’re dating a Sagittarius, maybe just keep an eye out — or better yet, keep things exciting enough that they never feel the urge to stray.
