Rockcliffe–Smythe is a neighbourhood in Toronto, Ontario, Canada. It was developed after World War II as part of the urbanization of the former suburb of York Township. It is in Ward 5 (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 Reeve of York West. Further to the east (beyond Hilldale road) is another pocket called Harwood. Harwood is bordered by creek in almost all directions.

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.

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. In April, 2015, Toronto Life listed Rockcliffe–Smythe as one of the top three neighbourhoods in Toronto for first time home buyers. “In the last 10 years there have been significant changes.” New retail development, like the Stockyards outdoor mall at the neighbourhood's southeastern corner, has revived some formerly barren lots, and the Junction's hot retail strip is just a short walk south.

Zigzagging from the north-west corner, where the Humber River and Eglinton Avenue West intersect:

• east along Eglinton to Jane Street
• south along Jane to Lambton Avenue
• east along Lambton, crossing Weston Road, to the north-south Mactier Subdivision/Weston Subdivision rail line
• south along the rail line to the former York/Old Toronto border
• following this border, crossing over St. Clair Avenue West, until it reaches the east–west Galt Subdivision railway line
• west along the rail line to the Humber River
• north along the river back to Eglinton Ave W

The area is centered by Jane Street, a north–south four-lane arterial road. To the west, Scarlett Road is another arterial road running northwest from Dundas Street to Eglinton, the northwest corner of the neighbourhood. The central east–west artery from Jane to Weston is Alliance Avenue and Lambton Avenue. To the east, Weston Road is a major four-lane arterial road that runs northwest.

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 is the York Community Centre, opened in 2017. The centre features 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.

In 2016 there was a total population of 22,246 people. Of which 51.7% were female and 48.3% were male; having an average age of 41.1 years.:
