Angle Tarn is a tarn in Cumbria, England, within the Lake District National Park, about a mile north-east of Hartsop.

[1] The lake is very distinctive in that it resembles a fish hook in shape.

It contains two rocky islets and a small broken peninsula.

This should not be confused with Angle Tarn (Langstrath), a smaller lake with the same name about 18.5 km to the northeast near Bowfell, also within the Lake District National Park.

Angle Tarn is a popular spot for overnight wild camping, especially on weekends and in the summer months.
