The Black Women's Caucus is a non-profit organization based in Washington state. The caucus was created at the State Women's Year Conference in July 1977. The organization's purpose is to "identify the barriers that prevent Black women from participating in mainstream society and to remove these barriers using their efforts, resources, and talents."

On January 7, 1978, a constitution governing the caucus was passed at a statewide meeting of Black women held in Seattle. Thelma Jackson of Olympia was elected as the first State President. The state organization was divided into four areas: the northwest, southwest, northeast, and southeast quadrants. Officers served for one year at the state level as well as the regional level. The activities of the caucus center on issues identified by Black women, then a work plan is created. This plan is updated and evaluated regularly to track progress.

The Black Women's Caucus sponsored the First Annual Black Summit Conference in Yakima in October 1978. In October 1979, the Second Summit Conference was held in Seattle. The third Annual Meeting was held in May 1980 in Seattle. Barbara Williams, the Executive Director of the Congressional Black Caucus, was the keynote speaker and workshop leader.

The caucus has been active in presenting cultural events important to African Americans' history, such as Juneteenth and Kwanzaa. Annually in June, the caucus has presented a luncheon with themes relevant to the African American community.
