A general election was held in the U.S. state of Wyoming on Tuesday, November 7, 1978. All of the state's executive officers—the Governor, Secretary of State, Auditor, Treasurer, and Superintendent of Public Instruction—were up for election. Democratic Governor Edgar Herschler won a narrow re-election to a second term, and Democrat Lynn Simons was elected Superintendent of Public Instruction, narrowly defeating incumbent Republican Robert G. Schroder. Republicans won the remainder of the statewide offices.
