Holdenby House is a historic house located in Northamptonshire, England. It was built in the 16th century by Sir Christopher Hatton, a close friend and advisor to Queen Elizabeth I. After Hatton died, the house became the palace of James I and then Charles I. Defeated in the English Civil War, Charles I was held here as a prisoner for 5 months.

Holdenby House is now a private family home welcoming visitors to its Grade I garden and Icarus Falconry Centre. Visitors can tour the house and its gardens, which feature a mix of formal and informal landscaping. The house is also home to a collection of fine art and historical artifacts, including a portrait of Queen Elizabeth I painted by Nicholas Hilliard.
