A village in a parish of the same name in the Carse of Gowrie, southeast Perth and Kinross, Longforgan lies 5 miles (8 km) west of Dundee. It was created a burgh of barony in 1672 and developed in association with Castle Huntly to the southwest.
Longforgan is home to best-selling author Rosamunde Pilcher (b.1924) and a street is named in her honour.
