Moses Bledso Corwin (January 5, 1790 – April 7, 1872) was a United States representative from Ohio.
Born in Bourbon County, Kentucky, Corwin spent the early part of his life on a farm, and attended rural schools. He studied law, and was admitted to the bar in 1812. He began practicing law in Urbana, Ohio.
Corwin was a member of the Ohio House of Representatives in 1838 and 1839, and was elected as a Whig to the Thirty-first United States Congress (March 4, 1849 – March 3, 1851), and was again elected to the Thirty-third Congress (March 4, 1853 – March 3, 1855).
Corwin's cousin, Thomas Corwin, was a U.S. Representative, Senator and Treasury Secretary; his cousin, Franklin Corwin, served one term as a Representative; his son, John A. Corwin, was his Democratic opponent in the 1848 Congressional election.
He engaged in the practice of law until his death at age 82. He was interred in Oak Dale Cemetery.
