John Douglas of Pinkerton (c.1709 – 20 June 1778) was a Scottish architect who designed and reformed several country houses in the Scottish Lowlands. His work deserves to be noted for what the 2002 history of Scottish architecture remarks as an approach "of relentless surgery or concealment.". His most notable works are Killin and Ardeonaig Church, Stirlingshire (1744); Archerfield House, East Lothian (1745); Finlaystone House, Renfewshire (1746–47), Wardhouse (Gordonhall), Insch, Aberdeenshire (1757); and Campbeltown Town House, Argyll and Bute (1758–60). Several of these are listed buildings.
