Ohio State Route 176 (SR 176) is a route linking Interstate 71 in Cleveland to Interstate 77 near Richfield.

State Route 176's route from I-71 to State Route 17 (Brookpark Road) is a limited-access highway. From 1968, it functioned as an exit off of I-71 and side streets, terminating at Denison Road and serving businesses in the industrial valley. As traffic volumes to suburbs such as Parma and Parma Heights increased – and to relieve traffic from I-77 to I-480 – the freeway portion of the route (known as the Jennings Freeway) was extended as originally planned to I-480 and Brookpark Road (SR 17), opening December 8, 1998. South of SR 17, the route is a grade-level road to its southern terminus.

Soon after its creation, SR 176 was extended to Akron, routed with US 21 (Cleveland-Massillon Road), over SR 92 (Ghent Road), replacing it, and along Market Street with a portion SR 18 (at the time, SR 18 followed Twin Oaks Road from Market Street) to downtown Akron, ending at the High Street/Broadway Street couplet (then SR 5, 8, and 261, now just SR 261). After the completion of I-77, SR 176 was relocated along Wheatley Road and moved on to I-77 from exits 143 to 138, before rejoining its original alignment. In the early 1970s, US 21 was changed to SR 21 at that location, and SR 176 was truncated at I-77 exit 143. SR 18 was also truncated, but realigned to follow the entirety of Market Street (which had also carried the also-truncated SR 8 east of High and Broadway) to end at SR 91.

Formerly applied to the Jennings Freeway section of SR 176, Route 176J is the section of Broadview Road between Brookpark Road (SR 17) in Brooklyn and Pearl Road (U.S. Route 42) in the Old Brooklyn neighborhood of Cleveland, which formerly carried SR 176. This roadway is intended to be turned over from the state system to the local governments ("J" suffix = "awaiting abandonment"), at which time the designation will be retired.
