Elizabeth Rudel Smith Gatov (April 27, 1911 – January 25, 1997) was a leader of the California Democratic Party who served as Treasurer of the United States, 1961–1962.

She was born in Montreal, the daughter of a Canadian-American industrialist who owned the Rudel Machinery Company, attended Smith College and graduated in 1937 from the University of Michigan.

In 1942, she moved to California when she married San Francisco businessman Frederick H. Smith IV, her third husband, whom she later divorced.

Mrs. Gatov returned to her Marin home from Washington in 1962 and remained active in Democratic politics for the next 20 years.

She held that Party post until her appointment in the Kennedy Administration, which also followed brief service in Sacramento as Deputy Labor Commissioner for Governor Pat Brown.
