King's Highway 7A, commonly referred to as Highway 7A, is a provincially maintained highway in the Canadian province of Ontario that serves as a bypass of Highway 7. The highway begins in the community of Manchester, where Highway 7 is concurrent with Highway 12, and travels east through Port Perry, Nestleton Station, Bethany and Cavan, ending at Highway 115 southwest of Peterborough. From there, Highway 7 can be reached via Highway 115 northbound. Near its midpoint the route is concurrent with Highway 35 for 1.5 kilometres (0.93 mi).

Highway 7A is 48.3 kilometres (30.0 mi) long, passing through the Regional Municipality of Durham, city of Kawartha Lakes and Peterborough County. Outside of the communities it serves, the highway passes through generally agricultural areas, though it enters the Oak Ridges Moraine near Highway 35.

The highway was designated in the 1930s in downtown Peterborough and shortly thereafter was extended west to Manchester. The causeways over Lake Scugog date back to the 1850s, and were repeatedly reinforced over the course of a century to reach their current state. During the 1950s, the construction of Highway 115 caused the route of Highway 7A to be modified. At the end of the decade, the causeways were reconstructed for the final time. The eastern end of the highway was reconfigured several times before arriving at its current routing after the 1960s.
