Lady Margaret Fortescue DL (13 December 1923 – 25 May 2013) was a British huntswoman and one of the country's richest private landowners, holding the Castle Hill estate and 20,000 acres (31 sq mi) of Exmoor.

[3][2] Fortescue was a fearless rider, and had several falls, and "after consulting her doctor and swallowing a few painkillers with wine, she almost invariably carried on".

[2] On her father's death in 1958, she inherited the Castle Hill estate, and became one of the country's largest private landowners.

[2] On 31 July 1948, Fortescue married Bernard van Cutsem (1916–1975), a racehorse trainer and breeder.

[1] Fortescue died at the Garden House, Castle Hill, Filleigh, on 25 May 2013, survived by both daughters.
