The Grand Lodge of Ohio was formed on January 4–8, 1808 by a convention of five of the six Masonic lodges then meeting in Ohio. The convention was held in the statehouse at Chillicothe and, on January 7, Rufus Putnam was elected Grand Master. Prior to formation of the Grand Lodge of Ohio, six lodges operated under authority of charters issued by their individual parent grand lodges in the eastern United States:
American Union Lodge No. 1 – chartered in 1776 by the Provincial Grand Lodge of New England, one of the predecessors of the current Grand Lodge of Massachusetts. Originally a military traveling lodge, it settled permanently in Marietta in June 1790.
Cincinnati Lodge No. 13 – chartered in 1806 by the Grand Lodge of Kentucky and located in Cincinnati. Its members had originally formed Nova Caesarea Lodge No. 10, chartered by the Grand Lodge of New Jersey in 1791, which charter they returned to that Grand Lodge previous to requesting a new one from the Grand Lodge of Kentucky.
Scioto Lodge No. 2 – chartered in 1805 by the Grand Lodge of Massachusetts and located in Chillicothe.
Erie Lodge was the driving force behind the formation of the Grand Lodge, and proposed the idea to the other lodges in the state. Due to a dispute over the credentials of its representative, James Kilbourne, New England Lodge was not present at the convention but is considered a founding lodge nevertheless. The Grand Lodge of Ohio has had a continual existence since 1808 and in 2018 had over 450 chartered lodges operating in Ohio with a total membership of over 75,000.
On December 4, 1994, Steven Reece, Grand Master of The Most Worshipful Prince Hall Grand Lodge of Ohio, formally requested recognition of his grand lodge by the Grand Lodge of Free & Accepted Masons of Ohio. The Grand Lodge granted fraternal recognition at its 186th annual session on October 20, 1995. The agreement between the two grand lodges states: The agreement was signed by Steven Reece, Grand Master, and Frederick E. Kelley, Sr., Deputy Grand Master of the Most Worshipful Prince Hall Grand Lodge of Ohio as well as James E. Olmstead, Grand Master, and Neil M. Smalley, Deputy Grand Master of the Grand Lodge of Free & Accepted Masons of Ohio.

Until 2012, the Grand Lodge's headquarters and museum were located in Worthington, Ohio. The Worthington building was built in 1955 and adjoined the lodge hall built in 1820 by New England Lodge No. 4. The 1820 building is said to be the oldest Masonic lodge hall west of the Appalachian Mountains. In 2012, the Grand Lodge moved its headquarters and museum to the campus of the Ohio Masonic Home in Springfield.
