John Henry Jarman II (July 17, 1915 – January 15, 1982) was a member of the US House of Representatives from Oklahoma for 26 years, from 1951 to 1977.

Jarman was born in Sallisaw, Oklahoma, on July 17, 1915, and graduated from Yale University in 1937 and from Harvard Law School in 1941.

[6] Jarman was reelected 11 times without serious difficulty, even as the Oklahoma City area trended increasingly Republican at the local level.

On January 24, 1975, Jarman switched parties and became a Republican in protest of the removals of F. Edward Hébert, Wright Patman, and William R. Poage from their committee chairmanships.

Edwards won the seat, and the district remained in Republican hands until Kendra Horn unseated Steve Russell in the 2018 midterm elections approximately 42 years later.
