Ohio History Connection, formerly The Ohio State Archaeological and Historical Society and Ohio Historical Society, is a nonprofit organization incorporated in 1885. Headquartered at the Ohio History Center in Columbus, Ohio, Ohio History Connection provides services to both preserve and share Ohio's history, including its prehistory, and manages over 50 museums and sites across the state. An early iteration of the organization was founded by Brigadier General Roeliff Brinkerhoff in 1875. Over its history, the organization changed its name twice, with the first occurring in 1954 when the name was shortened to Ohio Historical Society. In 2014, it was changed again to Ohio History Connection, in what members believed was a more modern and welcoming representation of the organization's image.

Duncan McArthur was a military officer and a Federalist and National Republican politician from Ohio. He served as the 11th governor of Ohio.
