1812 United States House of Representatives elections in Ohio

The 1810 census revealed dramatic population growth in Ohio since 1800, resulting in its representation increasing from a single Representative to six, resulting in the State being broken up into 6 districts, abolishing the OH's at-large congressional district. Jeremiah Morrow (Democratic-Republican), who had served since Ohio achieved statehood in 1803, retired to run for U.S. Senator, so that all six seats were open. Its elections were held October 13, 1812.
