The 2010 Ohio Attorney General election was held on November 6, 2010, concurrently with other statewide offices including a Class 1 Senate election as well as the Governor election. Incumbent Democratic Attorney General Richard Cordray who was elected in a 2008 special election ran for a full 4-year term but was defeated by Republican challenger and former 2-term United States senator Mike DeWine. Being decided by 1.2%, this was the closest statewide election in Ohio. Cordray and DeWine would later face off against each other again in the 2018 Governor election.
