Renfrewshire or the County of Renfrew is a historic county, registration county and lieutenancy area in the west central Lowlands of Scotland. It contains the local government council areas of Inverclyde, Renfrewshire and East Renfrewshire, as well as parts of Glasgow and is occasionally named Greater Renfrewshire to distinguish the county from the modern council area. The county borders the city of Glasgow and Lanarkshire to the east and Ayrshire to the south and west. The Firth of Clyde forms its northern boundary, with Dunbartonshire and Argyllshire on the opposing banks.
