Rockcliffe–Smythe is a neighbourhood in Toronto, Ontario, Canada. It was part of the former City of York before the amalgamation of Toronto in 1998. The boundaries are Eglinton Avenue West to the north, the Humber River and Jane Street to the west. It then proceeds south along Jane to Lambton, and follows Lambton past Weston Road to the north-south railway lines to the east. The boundary follows the railway south to the eastern boundary then veers south along neighbourhood streets until it reaches St. Clair Avenue West. The boundary then follows the railway line to the Humber River, and follows the Humber River north to Eglinton Avenue. It is in Ward 11 (York-South Weston) in the City of Toronto.
As with many neighbourhoods defined by the city, there are often more traditional names for pockets of the city. Directly north-east of Jane Street and St. Clair West is an area called Syme, named after George Syme. Further to the east (beyond Hilldale road) is another pocket called Harwood. Harwood is bordered by creek in almost all directions.
Rockcliffe–Smythe was mostly farm land during the 1800s. One of the first large-scale developments in the area was the opening of the Smythe gravel pit in the 1920s, by Conn Smythe. After World War II the gravel pit was used up. This led to the residential development of the surrounding area. Smythe made homes available to returning servicemen and families, losing money on each. The neighbourhood has retained the Smythe name ever since. Smythe Park exists today on the site of the pit and is the site of the Smythe Park Recreation and Community Centre.
More recently, Rockcliffe Smythe is re-asserting itself with a spate of new infrastructure developments. The northern part of the area will be within walking distance to Mount Dennis station on the Eglinton Crosstown  and the proposed SmartTrack Line. To the east of the neighbourhood the York Community Centre will be opening in early 2017. The centre is set to feature a double gymnasium, a running/walking track, a six-lane 25-metre indoor training pool, an indoor leisure pool, two multi-purpose rooms, and weight, aerobic and dance rooms.
The area is predominately residential in nature, mostly made up of single-family detached homes. There are apartment buildings along Jane Street, Scarlett Road, and Humber Boulevard. Rockcliffe–Smythe is known for having large amounts of green space including the centrally located Smythe Park. The entire western boundary is green space which includes Lambton Park and Scarlett Woods golf courses. Black Creek meets the Humber in the neighbourhood. The Black Creek enters the neighbourhood from the north-east, travelling through a concrete culvert in the center of Humber Boulevard and through concrete through parks and to the Humber.
BlogTO has identified Rockcliffe–Smythe as one of the top 5 Toronto neighbourhoods on the rise in 2017. In December 2016, Airbnb listed it sixth in its top 17 neighbourhoods to visit in 2017, based on a 497 per cent increase in bookings in 2016.
