King's Highway 11A, commonly referred to as Highway 11A, was the highway designation for an alternate route of Highway 11 in the Canadian province of Ontario. The north-south route paralleled Highway 11 (Yonge Street) within Toronto, serving as a secondary access to Downtown Toronto. It began at the York exit of the Gardiner Expressway (Highway 2) and travelled north on York Street to Front Street, where it transitioned onto University Avenue. It continued north on University Avenue to Queen's Park, where Highway 11A followed Queen's Park Crescent, encircling the Ontario Legislative Building, before continuing along Avenue Road. Highway 11A travelled along Avenue Road to Upper Canada College. It followed Lonsdale Road, Oriole Parkway, and Oxton Avenue around the campus and back to Avenue Road, which resumes north of the school. It continued north along Avenue Road to Highway 401, ending just north of the highway at Bombay Avenue.

Highway 11A was established in 1930, when the province built an extension of Avenue Road north from the city limits of the old City of Toronto to complete a parallel alternative to Highway 11. It connected to that route via the Hogg's Hollow Bridge, which had been completed the previous year to provide a level detour of the deep ravine of the West Don River. Although the streets it followed within old Toronto were not maintained by the province, they were signed as part of the highway as a city-maintained Connecting Link for continuity, which was a policy that also applied to other highways that followed city streets. The Hogg's Hollow Bridge was incorporated into Highway 401 upon its completion in 1952, truncating Highway 11A at the interchange with the new freeway. When Metropolitan Toronto was formed in 1953, most provincial routes within its boundaries which were not already connecting links, including Highway 11A, were designated as such. The short and then-recently-urbanized northernmost section of the highway was given Connecting Link status in early 1954 and the whole route continued to be signed until 1997 when it was fully decommissioned.^[2]
