State Trunk Highway 794 (Highway 794, STH-794, WIS 794), officially the John R. Plewa Memorial Lake Parkway or the Lake Parkway, is a 4.76-mile (7.66 km) state highway in Milwaukee County, Wisconsin, United States, that goes north–south from downtown Milwaukee to its southern suburbs. WIS 794 is the highest numbered Wisconsin state highway in the state trunk highway system. WIS 794 is one of only two numbered state trunk highways, along with WIS 39, that share a number designation with an Interstate or US highway within the state's borders. Wisconsin Department of Transportation (WisDOT) policy otherwise prohibits dual designations within the state trunk highway system, a situation it had been able to maintain until the US 51 freeway was designated as a northward extension of Interstate 39.
