Hamilton Dudley Coleman (May 12, 1845, New Orleans, Louisiana – March 16, 1926, Biloxi, Mississippi) was a businessman and politician who served one term in the United States House of Representatives from Louisiana's 2nd congressional district, 1889-91.
Coleman served in Washington Artillery in the Army of Northern Virginia during the American Civil War, and was part of the Confederate army that surrendered at Appomattox.
He returned to New Orleans and became a manufacturer and dealer of farm equipment, and an organizer of New Orleans's first electric lighting company. He was elected as a Republican to Congress in 1888, but lost his bid for reelection to Matthew D. Lagan, the previous holder of the seat. Coleman was the last Republican elected to the House from Louisiana until David C. Treen in 1973. He was the last Republican to hold this seat, until Joseph Cao won it from Bill Jefferson in 2008.
Coleman ran for Congress two more times, for governor twice, and for lieutenant governor once, losing each time. From 1899-1905, he was the melter and refiner for the United States Mint in New Orleans. He died in Biloxi in 1926 and is buried at Metairie Cemetery in New Orleans.
