Thakeham is a village and civil parish located north of the South Downs in the Horsham District of West Sussex, England.

Towards the end of World War 1, from February 1917 until February 1918, there was a Royal Flying Corps Home Defence day and night landing ground [5] in the north of Thakeham Parish abutting Shipley Parish south/east of Sincox Lane and east of Ingrams Furze.

Local newspapers also promoted further air displays by C W A Scott and Tom Campbell Black in April and June 1936 but these may well have been cancelled as neither event was reported afterwards.

Land use in the parish is predominantly agricultural, dominated by farming and wooded areas (with outstanding bluebell displays in the spring).

Heritage assets in the parish include the 13th century Church of the Holy Sepulchre in Warminghurst, and Little Thakeham,[6] a Grade I listed country house on Merrywood Lane, designed by the architect Edwin Lutyens in 1902.
