Coop House, near Netherby in Cumbria, England, is a small building by the River Esk, erected about 1772 as part of a salmon fishery project, and restored in the 1990s by the Landmark Trust.

[1] It is situated on the south bank of the River Esk and west of Netherby Hall.

The Revd Robert Graham of Netherby Hall made many improvements to his estate, and endeavoured to establish a salmon fishery, which involved building a weir in the river in 1770, and creating coops, which may have been holding pens for the fish.

[1][2] The building is of red sandstone, and it originally consisted of one room with a projecting bay to view the river.

[2] In 1992, the Landmark Trust obtained a lease for the property from Sir Charles Graham, and from 1994 there was restoration, directed by the architect Rosalind Taylor.
