Ohio State Route 225 is a north-south highway in Portage County and northeastern Stark County. It runs north out of Alliance to a point west of Newton Falls. As Ohio Route 183 runs north out of Alliance, it bends northwesterly, but the northward street continues as the southern beginning of Ohio Route 225. The route continues north from there, jogging easterly on US Route 224 to continue north again. The northern end of Ohio Route 225 is at Ohio Route 5, between Newton Falls and Ravenna.
