The Twenty-first Oklahoma Legislature was a meeting of the legislative branch of the government of Oklahoma, composed of the Oklahoma Senate and the Oklahoma House of Representatives. The state legislature met in regular session from January 7 to May 8, 1947, during the term of Governor Roy J. Turner. The session was marked by a gunfight on the Senate floor, in which a state representative shot Tom Anglin, a state senator and former Speaker of the Oklahoma House of Representatives, in the hip, on May 7, 1947.
