John Thomas Peavey (September 1, 1933 – June 16, 2024) was an American rancher and Democratic politician from Carey, Idaho. Peavey served in the Idaho Senate from 1969 to 1976 and from 1978 to 1994.

From a young age Peavey worked on the ranch founded by his grandfather, U.S. Senator John Thomas. In 1969 he succeeded his mother, Mary Brooks in the Idaho Senate as a Republican after she was appointed director of the United States Mint by President Richard M. Nixon.

In 1974, after repeated attempts to pass a Sunshine Law; a law requiring lobbyists to register and political campaign disclosure, in the legislature were unsuccessful, Peavey led a successful statewide campaign to pass one by ballot initiative.[citation needed]

In 1994 Peavey was the Democratic nominee for lieutenant governor. He was defeated by the Republican incumbent Butch Otter, who was later elected governor in 2006.

Peavey died on June 16, 2024, at the age of 90.
