Clarence C. "Taddy" Aycock (January 13, 1915 – January 6, 1987), a conservative Democrat from Franklin in St. Mary Parish, was the only three-term lieutenant governor in 20th century Louisiana history. He served from 1960 to 1972. Aycock failed in his only bid for governor in the 1971 Democratic primary. Few lieutenant governors in Louisiana have been elected directly to the governorship; former Governor Kathleen Babineaux Blanco of Lafayette, is a prominent exception.
