Jeremiah Henry Murphy (February 19, 1835 – December 11, 1893) was a two-term Democratic U.S. Representative from Iowa's 2nd congressional district.

He was an unsuccessful candidate for election in 1876 to represent Iowa's 2nd congressional district in the Forty-fifth Congress.

However, when seeking a third term in 1886, Murphy was defeated in the Democratic district convention, by Walter I. Hayes.

Between the Civil War and the Great Depression, Murphy and Hayes were the only two Democratic congressmen from Iowa to serve two or more full terms.
