Theophilus Eugene "Bull" Connor (11 July 1897 - 10 March 1973) was a police official in the Southern United States during the American Civil Rights Movement and a staunch advocate of racial segregation.

Connor was born in Selma, Alabama.

As the Public Safety Commissioner of Birmingham, Alabama in the 1960s, he became infamous for using fire hoses and police attack dogs against unarmed, nonviolent protest marchers. The spectacle of this being broadcast on national television helped to catalyse major social and legal change in the South and helped in large measure to assure the passage by Congress of the Voting Rights Act of 1965, so ironically Connor's tactics helped to bring about the very change that he was opposing.
