Blackwaterfoot (Scottish Gaelic: Bun na Uisge Dubh lit.

'foot of the black water') is a village on the Isle of Arran in the Firth of Clyde, Scotland.

It is one of the smaller villages of Arran and home to one of Europe's two 12-hole golf courses.

Nearby Drumadoon Point is home to the largest Iron Age fort on Arran.

Further north is the King's Cave, reputed to be a hiding place of Robert the Bruce.
