The General Federation of Women's Clubs (GFWC), founded in 1890 during the Progressive Movement, is a federation of approximately 2,300 women's clubs in the United States which promote civic improvements through volunteer service. Community Service Projects (CSP) are organized by local clubs for the benefit of their communities or GFWC's Affiliate Organization (AO) partnerships. GFWC maintains nearly 60,000 members throughout the United States and internationally. GFWC is one of the world's largest and oldest nonpartisan, nondenominational, women's volunteer service organizations. The GFWC headquarters is located in Washington, D.C.

The woman's club movement was a social movement that took place throughout the United States that established the idea that women had a moral duty and responsibility to transform public policy. While women's organizations had existed earlier, it was not until the Progressive era (1896–1917) that they came to be considered a movement. The first wave of the club movement during the progressive era was started by white, middle-class, Protestant women, and a second phase was led by African-American women.
