Govan Old Parish Church was a parish church in the Church of Scotland, serving Govan in Glasgow. It was also known as "St Constantine's". Since 2007, the congregation has become part of Govan and Linthouse Parish. Govan Old Church is no longer used for regular Sunday services, but the building remains open and is used for occasional services, including midweek services. The dedication is to Saint Constantine of Strathclyde whose shrine at Govan is still in existence.
