Yew Tree Tarn is a small lake in the English Lake District situated in between the towns of Ambleside and Coniston. The tarn was formed when the local landowner dammed the Yewdale Beck in the 1930s and stocked the lake with trout. Currently, fishing for brown and rainbow trout is controlled and managed by the Coniston and Torver Angling Association. A usable footpath runs around the periphery of the tarn not bordered by the main road.
