Marian Clark (born Marian Alice Clark; June 25, 1912 – February 26, 1963) was an American scriptwriter for radio and television series during the 1950s and early 1960s, most notably for the long-running, iconic Western series Gunsmoke, which aired on CBS Radio from 1952 to 1961 and on CBS Television for two decades. Clark ranks among the most prolific writers in the history of Gunsmoke; and prior to her work on that series, she was also one of the first women in American radio to be employed full time as a news writer for a major regional station and affiliate of a national broadcasting network.
