Ageneral election was held in the U.S. state of Wyoming on Tuesday, November 5, 1918. All of the state's executive officers—the Governor, Secretary of State, Auditor, Treasurer, and Superintendent of Public Instruction—were up for election. Republicans won all statewide offices by wide margins, and with Robert D. Carey's defeat of Frank L. Houx, picked up the governorship following two consecutive losses to Democrats.
Incumbent Democratic Governor Frank L. Houx, who ascended to the governorship following John B. Kendrick's election to the U.S. Senate in 1916, ran for re-election to a full term. He was opposed by Republican nominee Robert D. Carey, the Chairman of the State Highway Commission and the son of former Governor Joseph M. Carey, in the general election. Carey defeated Houx by a decisive margin.

Incumbent Republican Superintendent of Public Instruction Edith K. O. Clark declined to seek re-election, creating an open seat. Katharine A. Morton, the former State Librarian, won a plurality of the vote in the Republican primary and advanced to the general election.
