Barnby Dun with Kirk Sandall is a civil parish in the Metropolitan Borough of Doncaster in South Yorkshire, England.

[1] The parish covers Barnby Dun and Kirk Sandall, both parts of the Doncaster urban area.

[3] Barnby Dun was home to the Thorpe Marsh Power station before its closure in the middle 1990s.

Barnby Dun was first named House-on-Dun after the River Don running beside it, however, the name was changed in the late 19th century to Barnby Dun due to the farms and farming lands surrounding the area on the north and west sides.

[6] The old school, as it is known now, with one classroom was paid for originally from local charities and the church fund.
