Individualist feminism, or ifeminism, advocates the equal treatment of men and women as individuals under just law. The core principle of individualist feminism is that all human beings have a moral and legal claim to their own persons and property, not to any sort of affirmative action policies or privileges. Because of this, it is sometimes also called libertarian feminism.

It has no connection to the classical radical feminist movement, and in most parts of Europe is viewed as postmodern feminism because of the pluralistic view on female nature.

The original US group known as ifeminists is strongly associated with The Independent Institute, a libertarian group. Radical feminists often disapprove of this, because most of The Independent Institute's leading positions are filled by men, even though the actual ifeminist group is headed by women.
