East Renfrewshire (Scots: Aest Renfrewshire; Scottish Gaelic: Siorrachd Rinn Friù an Ear) is one of 32 council areas of Scotland. Until 1975, it formed part of the county of Renfrewshire for local government purposes along with the modern council areas of Renfrewshire and Inverclyde. Although no longer a local authority area, Renfrewshire still remains the registration county and lieutenancy area of East Renfrewshire.
The East Renfrewshire local authority was formed in 1996, as a successor to the Eastwood district, along with Barrhead, which came from Renfrew district. Its longest border is with East Ayrshire, followed by the City of Glasgow, then Renfrewshire and South Lanarkshire, followed by its extremely short border with North Ayrshire.
