Easedale Tarn is a tarn in the centre of the English Lake District, about two miles west of the village of Grasmere. It lies in a hollow between Tarn Crag to the north and Blea Rigg to the south, about 910 feet or 280 metres above sea level. The hollow was formed by a small corrie glacier, and is believed to have filled with water around 11,000 years ago when the ice finished melting.
