Rape crisis centers (RCCs) are community-based organizations affiliated with the anti-rape movement that work to help victims of rape, sexual abuse, and sexual violence. Central to a community's rape response, RCCs provide a number of services, such as victim advocacy, crisis hotlines, community outreach, and education programs. As social movement organizations, they seek to change social beliefs and institutions, particularly in terms of how rape is understood by medical and legal entities and society at large. There is a great deal of diversity in terms of how RCCs are organized, which has implications for their ideological foundations, roles in their communities, and the services they offer.
