John J. Hickey Democratic Milward Simpson Republican The 1962 United States Senate special election in Wyoming was held on November 6, 1962.

Following the death of Senator-elect Keith Thomson after his election to the Senate in 1960, Democratic Governor John J. Hickey appointed himself to fill the vacancy.

A special election was held to fill the remaining four years of the term in 1962, and Hickey faced a strong challenge from former Republican Governor Milward Simpson in a rematch of the 1958 gubernatorial election.

Despite a political environment largely favorable to Democrats nationwide, Democratic candidates faced strong headwinds in Wyoming.

Senator Hickey overwhelmingly lost re-election to Simpson as Democratic Governor Jack R. Gage lost re-election by a wide margin, as well.
