Intersectionality is an analytical framework for understanding how a person's various social and political identities combine to create different modes of discrimination and privilege. Intersectionality identifies multiple factors of advantage and disadvantage. Examples of these factors include gender, caste, sex, race, ethnicity, class, sexuality, religion, disability, weight, and physical appearance. These intersecting and overlapping social identities may be both empowering and oppressing.

Intersectionality broadens the scope of the first and second waves of feminism, which largely focused on the experiences of women who were white, middle-class and cisgender, to include the different experiences of women of color, poor women, immigrant women, and other groups. Intersectional feminism aims to separate itself from white feminism by acknowledging women's differing experiences and identities.

The term intersectionality was coined by Kimberlé Crenshaw in 1989.^: 385 She describes how interlocking systems of power affect those who are most marginalized in society. Activists use the framework to promote social and political egalitarianism. Intersectionality opposes analytical systems that treat each axis of oppression in isolation. In this framework, for instance, discrimination against black women cannot be explained as a simple combination of misogyny and racism, but as something more complicated. Intersectionality engages in similar themes as triple oppression, which is the oppression associated with being a poor or immigrant woman of color. Intersectional analysis aligns very closely with anarcha-feminist power analysis frameworks.

Criticism includes the framework's tendency to reduce individuals to specific demographic factors, and its use as an ideological tool against other feminist theories. Critics have characterized the framework as ambiguous and lacking defined goals. As it is based in standpoint theory, critics say the focus on subjective experiences can lead to contradictions and the inability to identify common causes of oppression. An analysis of academic articles published through December 2019 found that there are no widely adopted quantitative methods to investigate research questions informed by intersectionality and provided recommendations on analytic best practices for future research. An analysis of academic articles published through May 2020 found that intersectionality is frequently misunderstood when bridging theory into quantitative methodology.
