The Ohio Military Reserve (OHMR) is one of three separate components that make up the Ohio State Defense Force (SDF). Like other SDF's the Ohio Military Reserve functions as a reserve to the Ohio National Guard.

State Defense Forces are not eligible for federal funding and must request their assets from the state. The OHMR had an organizational budget of $77,491 for Ohio Fiscal Year 2025. Personnel are unpaid for their drill weekends and training. They must also provide their own uniforms and equipment.

The OHMR serves under the Adjutant General and is headquartered at the Haubrich Armory in Columbus, Ohio.

As of 2023, the OHMR operates as a brigade level entity. Its sole brigade is the 4th Civil Support and Sustainment Brigade. For Ohio Fiscal Year 2025, the OHMR had a total authorized strength of 744 soldiers, of which 160 were filled.

The OHMR has a "sister service", the Ohio Naval Militia which operates out of Camp Perry, located near Port Clinton, Ohio.
