Duncombe Park is the seat of the Duncombe family who previously held the title Earls of Feversham. The title became extinct on the death of the 3rd Earl in 1963, since when the family have continued to hold the title Baron Feversham. The park is situated one mile south-west of Helmsley, North Yorkshire, England and stands in 300 acres (120 ha) of parkland. The estate has a commanding location above deeply incised meanders of the River Rye within the North York Moors National Park.

Baron Feversham is a title that has been created twice, once in the Peerage of Great Britain and once in the Peerage of the United Kingdom. The first creation, in the Peerage of Great Britain, came in 1747 when Anthony Duncombe, who had earlier represented Salisbury and Downton in the House of Commons, was made Lord Feversham, Baron of Downton, in the County of Wilts. He had previously inherited half of the enormous fortune of his uncle Sir Charles Duncombe. However, Lord Feversham had no sons and the barony became extinct on his death in 1763. The peerage was revived in the Peerage of the United Kingdom in 1826 in favour of his kinsman Charles Duncombe, who was created Baron Feversham, of Duncombe Park in the County of York. He was a former Member of Parliament for Shaftesbury, Aldborough, Heytesbury and Newport. Duncombe was the grandson of Thomas Duncombe, son of John Brown by his wife Ursula Duncombe, aunt of the first Baron of the 1747 creation. Ursula had inherited the other half of her brother Sir Charles Duncombe's fortune. Lord Feversham son, the second Baron, sat as a Conservative Member of Parliament for Yorkshire and the North Riding of Yorkshire.
