Abstract   Feminism has historically been peripheral to the study and practice of criminal justice, mainstream criminologists have not been widely exposed to feminist perspectives. This has contributed to perceptions that criminology is about men and feminism is only about women. Consequently, many criminologists and criminal justice practitioners have yet to understand, much less appreciate, the importance of feminism's contribution to criminology. To address this problem, this article explains some of the major feminist insights in the interrelated areas of epistemology, theory, methodology, and policy. Examples from the criminal justice literature are used to illustrate both the basis for feminist concerns as well as the diversity of feminist scholarship.
