Cockersand Abbey chapter house is a mausoleum in the English village of Thurnham, Lancashire. A Grade I listed building and formerly part of Cockersand Abbey, it dates to 1230.^[1] It was used as a family mausoleum by the Daltons of Thurnham Hall during the 18th and 19th centuries.^[2] The land was acquired by the Daltons shortly after 1556, when Sir Robert Dalton married Ann Kitchen.^[3]

Cockersand Abbey has existed from the late 12th century. The building is constructed of red sandstone rubble and has a slate roof. Its plan is octagonal although the west side has been squared off. At some point (probably the mid-18th century) it was converted into a family burial chamber.^[4][5]
