State Route 237 is a nearly 14-mile (23 km) north–south signed route in Cuyahoga County, Ohio. Its southern terminus is at SR 82 in Strongsville, and its northern terminus is in Lakewood where US 20 joins the US 6/SR 2 concurrency.

The portion of the route that connects Cleveland Hopkins International Airport to I-480 and I-71 is known as the Berea Freeway or the Airport Freeway. This portion was converted from expressway to freeway between 1983 and 1987.

The original route of SR 237 was incorporated into the southern section of Ohio State Route 79. Most of the current routing of SR 237 was originally Ohio State Route 232.
