Markenfield Hall is an early 14th-century moated manor house about 3 miles (5 km) south of Ripon, North Yorkshire, England.

The house is an L-shaped castellated block, with a great hall that stands above an undercroft and was originally reached by an exterior stone staircase.

[7] Most years, the house is open for public tours in the afternoons for several weeks in May and June, and the property is also marketed as a wedding venue.

[8] Due to the COVID-19 pandemic in the United Kingdom however, the Hall and grounds remained temporarily closed as of June 2020 but the owners expected to be able to reopen in July, with tours not exceeding ten persons at a time on specific dates.

The present house was built for John de Markenfield, an associate of Piers Gaveston and a servant of Edward II.

[10] Sir Thomas Markenfield was appointed High Sheriff of Yorkshire for 1484 and fought on the side of Richard III at the Battle of Bosworth.

[12] The property descended to the 7th Baron Grantley, John Richard Brinsley,[13] who began a restoration project in 1980 to convert the hall from a farmhouse into a family home.

The historic listing summary (not recently updated)[6] provides this description of the Hall and its modifications:Fortified manor house, with offices and outbuildings.

[18] Lady Deirdre married her current husband, Ian Bayley Curteis, the dramatist and television director, in 2001.
