Slains Castle (otherwise known as Old Slains Castle) is a ruined castle near Collieston in Aberdeenshire, Scotland. It is not to be confused with New Slains Castle, a separate building located five miles (eight kilometres) northeast. Originally built in the 13th century, with the surviving remains largely dating from the 15th century, it was partly destroyed in 1594.
