Claudette Colvin was an American pioneer of the 1950s civil rights movement and nurse aide. On March 2, 1955, she was arrested at the age of 15 in Montgomery, Alabama, for refusing to give up her seat to a white woman on a crowded, segregated bus. It occurred nine months before the similar, more widely known incident in which Rosa Parks, secretary of the local chapter of the National Association for the Advancement of Colored People (NAACP), helped spark the 1955 Montgomery bus boycott.
Colvin was one of four plaintiffs in the first federal court case filed by civil rights attorney Fred Gray on February 1, 1956, as Browder v. Gayle, to challenge bus segregation in the city. In a United States district court, Colvin testified before the three-judge panel that heard the case.
