South Gyle (pronounced /ɡaɪl/) is an area of Edinburgh, Scotland, lying on the western edge of the city and to the south and west of an area of former marshland once known as the Gogarloch, on the edge of Corstorphine. Most of the buildings in the area are of recent origin, dating from the later 1980s, 1990s, and early 21st century, with the exception of some farm workers' cottages and an early 1970s council estate abutting South Gyle railway station.

South Gyle can be neatly divided into two main zones – a residential one, incorporating Gogarloch and the neighbouring area centred on South Gyle Mains; and a commercial/business one which incorporates the Gyle Shopping Centre, Edinburgh Park, Gyle Park (an actual park, but with some shopping centres near it), and South Gyle Crescent. The Royal Bank of Scotland and sportscotland are all based in this district. The Lochside development also features a number of busts of Scottish poets.

"Gyle", which is pronounced with a hard "g", is of uncertain etymology. It has been suggested that it comes from an old Gaelic word "goill" meaning a "bog", which would make sense given the former Gogar Loch in the area.

There is also a North Gyle about one mile (two kilometres) away, which is named after a local farm. This is incorporated in some street names in that area.

Edinburgh Airport is nearby at Ingliston, and also close is the city bypass (A720), connecting to several major routes into the city.

South Gyle has two railway stations: South Gyle station is on the line between Edinburgh and Fife, and Edinburgh Park station provides services to Edinburgh, Stirling and Dunblane, Bathgate and to Glasgow Queen Street low-level.

Lothian Buses services 2, 12, 18, 21, 22, 22A, 32 and 36 serve the area.

Edinburgh Trams serve the area with stops at Bankhead, Edinburgh Park Station, Edinburgh Park Central (Lochside) and The Gyle Shopping centre.
