Men Are from Mars, Women Are from Venus is a relationship self-help book by John Gray, first published in 1992. The book explores the idea that men and women have fundamentally different emotional needs, communication styles, and ways of handling stress—metaphorically describing them as being from different planets.

John Gray explains common misunderstandings between partners and offers practical advice on improving communication, building empathy, and strengthening romantic relationships. He suggests that men often seek solutions and independence when facing problems, while women typically seek understanding and emotional connection. By recognizing and respecting these differences, couples can reduce conflict and create more fulfilling relationships.

The book became an international bestseller and remains one of the most well-known guides on relationship dynamics and gender communication.
