Clachan of Campsie or Campsie Glen () is a settlement now in the East Dunbartonshire area of Scotland. It was formerly part of the county of Stirlingshire. It is situated to the south of the Campsie Fells at the foot of Campsie Glen where the Finglen and Aldessan Burns meet, forming the Glazert Water which then flows south-east until it joins the River Kelvin near Kirkintilloch.
