1970 Connecticut Attorney General election

The 1970 Connecticut Attorney General election took place on November 3, 1970, to elect the Attorney General of Connecticut. Incumbent Democratic Attorney General Robert K. Killian was appointed to the office by Governor John N. Dempsey in 1967 to fill the vacancy left by Harold M. Mulvey, who resigned a year into his term to accept an appointment to the Connecticut Superior Court.

Killian was elected to a full term in his own right, defeating Republican nominee Donald T. Dorsey by 1,763 votes, a margin of just 0.17%. As of 2024, this was the last time the Attorney General of Connecticut was elected by less than a 5-point margin.
