Derryclare Lough (Irish: Loch Dhoire an Chláir)[1] is a freshwater lake at the entrance of the Inagh Valley, in Connemara, County Galway, in the west of Ireland.

Derryclare Lough is located about 20 km (12 mi) east of Clifden on the N59 road.

[5] Irish fishing author, Peter O'Reilly, said about Derryclare Lough that "This fishery has everything".

[6][7] The lake is a popular scenic location, and extensively photographed, and offers views directly into the Glencoaghan Valley of the Twelve Bens and the peaks of the Glencoaghan Horseshoe, a 16–kilometre 8–9 hour route that is considered one of Ireland's best hill-walks.

[4][8][9] The lough bounds the 19-hectare Derryclare Nature Reserve a Statutory Nature Reserve, and the larger 789-hectare Derryclare Wood, a Coillte owned commercial conifer forest.
