Frank Ruff Parker III (May 11, 1940 – July 10, 1997) was an American civil rights lawyer and voting rights activist. Beginning in 1981, while working for The Lawyers' Committee for Civil Rights Under Law, he directed the Voting Rights Project, where he helped secure from the United States Congress a 25-year extension of the Voting Rights Act of 1965. During his 12 years as Director of the Voting Rights Project, he launched a program to enforce the guarantees of the Voting Rights Act on a nationwide level through litigation and public education, and was a leader in the five-year struggle to enact the National Voter Registration Act of 1993. In 1990, he authored an award-winning book on the impact of the Voting Rights Act in Mississippi, Black Votes Count: Political Empowerment in Mississippi After 1965.
