'''State Route 561''' ('''SR 561''') is a north–south state highway in the southwestern portion of the U.S. state of Ohio. Its southern terminus is at U.S. Route 50 approximately {{convert|9|mi|km}} east of Downtown Cincinnati – this point also serves as the western termini for both SR 32 and SR 125; the route’s northern terminus is at its intersection with Vine and Seymour Streets. The route takes many different names along its length, being first known as Linwood Avenue, Observatory Avenue, and Edwards Road in Cincinnati; then it is named Smith Road and Carthage Avenue as it passes through Norwood; its final stretch in Cincinnati once again is as Seymour Avenue.

==History== In 1938, the original route was certified. It was originally routed from {{convert|2|mi|km}} north of its current southern terminus to U.S. Route 42. SR 561 was then extended to the south to its current terminus on a former segment of U.S. Route 50 in 1941. In 1947, the northern terminus was moved one mile (1.6 km) north of State Route 4. It was moved along a road that was previously not numbered.{{Cn|date=July 2025}}
