King's Highway 2A, commonly referred to as Highway 2A, was the designation of five separate provincially maintained highways in the Canadian province of Ontario. Highway 2A was an alternate route to Highway 2 in Chatham, London and Cornwall; these routes were all eventually redesignated. Highway 2A was also a highway that extended from Windsor to Tilbury, which was redesignated as Highway 98 in 1938.

The final and most familiar section of highway to be designated Highway 2A was the bypass of Highway 2 (Kingston Road) between Toronto and Newcastle, most of which became part of Highway 401 (formerly the Toronto Bypass) in July 1952. A short stub that wasn't incorporated into Highway 401 was all that remained of Highway 2A, consisting of a 3.4 km (2.1 mile) dual carriageway connecting Highway 401 with Kingston Road. Despite losing its provincial highway status in 1998, Highway 2A was never renamed and is now part of Toronto's municipal expressway system.
