Misandry () is the hatred of, contempt for, or prejudice against men.

Men's rights activists and other masculinist groups have criticized modern laws concerning divorce, domestic violence, conscription, circumcision (known as male genital mutilation by opponents), and treatment of male rape victims as examples of institutional misandry.

In the Internet Age, users posting on manosphere internet forums such 4chan and subreddits addressing men's rights activism (MRAs), claim that misandry is widespread, established in the preferential treatment of women, and shown by discrimination against men. This viewpoint is denied by most sociologists, anthropologists and scholars of gender studies who counter that misandry is not at all established as a cultural institution, nor is it equivalent to misogyny which is many times more prevalent in scope, far more deeply rooted in society, and more severe in its consequences. Scholars criticize MRAs for promoting a false equivalence between misandry and misogyny.^: 132 The modern activism around misandry represents an antifeminist backlash, promoted by marginalized men.

Misandry can be racialized. According to some researchers in Black Male Studies such as Tommy J. Curry, Black men and boys face anti-Black misandry. E. C. Krell, a gender researcher, uses the term racialized transmisandry describing the experience of Black transmasculine people.
