Hartham Park is a Georgian manor house in Wiltshire, England, about 1+1⁄4 miles (2.0 km) north of the town of Corsham.

Originally designed by James Wyatt, and set today in 50 acres (20 ha), it has within its grounds a stické tennis court.

In the 1830s his son Henry Hall Joy undertook a land swap with Sir Benjamin Hobhouse, in which he took ownership of the adjacent Hartham House, which had historically been owned by the Duckett family.

The house was remodelled and the grounds were landscaped by Harold Peto, including a Dutch water garden, subsequently largely overbuilt in a 1960s redevelopment.

Hartham also became a focal point for political and recreational life in North Wiltshire, with records showing numerous stays for his friends Winston Churchill and Prince Arthur, Duke of Connaught and Strathearn, the third son of Queen Victoria who enjoyed the local game shooting.

Started in an artillery building at the gunnery range at Shoeburyness, Essex in 1877, courts were built throughout the British Empire, and particularly in country houses.

Subsequently, Hartham Park estate was purchased by the J&W Nicholson & Co. family of gin makers, who took up residence during the Second World War.
