Polharrow Burn is a small watercourse in Dumfries and Galloway, Scotland, in the historic county of Kirkcudbrightshire.

It rises in Loch Harrow and flows towards St John's Town of Dalry before joining the Water of Ken.

[1][2] Polharrow is a Gaelic name formed from the words poll 'stream' and airbhe 'wall, fence'.

The Scots word burn has been added later, when the meaning of poll in the name became opaque.

He lived in his retirement at Glendarroch in St John's Town of Dalry and died in 1971.
