Thornliebank (Scots: "Thonliebank", Scottish Gaelic: "Bruach nan Dealgan") is a suburban area in East Renfrewshire, in the west central Lowlands of Scotland. Part of the Greater Glasgow conurbation, it is located on the Auldhouse Burn about south of Glasgow city centre, and just outside the city's administrative boundaries (the closest neighbourhoods within Glasgow, to the west and north of Thornliebank, being Arden, Carnwadric, Eastwood, Jenny Lind and Mansewood). The neighbouring East Renfrewshire town of Giffnock lies directly to the east, with Rouken Glen Park to the south.
