The Glasgow and Paisley Joint Railway was the section of railway line between Glasgow Bridge Street railway station and Paisley, in the west of Scotland. It was constructed and operated jointly by two competing railway companies as the stem of their lines to Greenock and Ayr respectively, and it opened in 1840. The Joint Committee, which controlled the line, built a branch to Govan and later to Cessnock Dock, and then Prince's Dock. The line is still in heavy use today as the eastern end of the Inverclyde Line and the Ayrshire Coast Line.
