Gourock (About this sound listen ; Scottish Gaelic: Guireag pronounced [kuɾʲak]; GOOR-uck) is a town falling within the Inverclyde council area and formerly forming a burgh of the county of Renfrew in the west of Scotland. It has in the past functioned as a seaside resort on the Firth of Clyde. Its principal function today, however, is as a popular residential area, extending contiguously from Greenock, with a railway terminus and ferry services across the Clyde.
