Arthur W. St. Clair (died 1877) was an African-American community leader in Brooksville, Florida, who was murdered in 1877 by a mob days after he presided over the marriage of a black man and a white woman in the area that is now Dade City, Florida.[1][2] Controversy followed as efforts to investigate the white men accused of killing him were stymied. The courthouse was destroyed in a fire.[3]
