Red Tarn is a small lake in the eastern region of the English Lake District, in the county of Cumbria. It is high up on the eastern flank of Helvellyn, beneath Striding Edge and Catstye Cam. The lake is along with three others in Lake District is a habitat for the very rare endangered Schelly fish. Red Tarn was a dam in the nineteenth century, using boulders, which raised the water level some eight or nine feet in order to supply power to the Greenside Lead Mine at Glenridding.

It lies at an altitude of 718 metres (2,356 feet), with a depth of 25 metres (82 feet).

The tarn is one of two of the same name in the Lake District. A second, much smaller Red Tarn lies between Pike of Blisco and Cold Pike, west of the Langdales.
