Alum Pot is a pothole with a large open shaft at a surface elevation of 343 metres (1,125 ft)[2] on the eastern flanks of Simon Fell, North Yorkshire, England.

Alum Pot has variously been known as Allan, Alan, Allen, Hellen and Hell'n.

[3] In 1847 John Birkbeck undertook the first partial descent of Alum Pot from Long Churn Cave which did not reach the floor of the shaft.

[3] Another successful complete descent of Alum Pot took place in 1870, when a group of people were lowered to the floor using a cage and windlass operated by navvies working on the Settle–Carlisle Line.

[5] In July 1936 Mabel Binks became the first caving fatality in the Yorkshire Dales when she was hit by a rock falling down the Main Shaft.
