Swallowfield Park is a Grade II* listed[1] stately home and estate in the English county of Berkshire.

Swallowfield Park was the home of the Backhouse family from the late 16th century, who had lived in a now demolished Tudor mansion.

[2] The present house at Swallowfield Park was erected in 1689 by Henry Hyde, 2nd Earl of Clarendon, when he acquired the estate on his marriage to William Backhouse's daughter Flower.

[4] In 1717, Thomas 'Diamond' Pitt, the Governor of Fort St. George, bought Swallowfield Park from Edward Hyde, reputedly using part of the proceeds of his sale of the Regent Diamond to Philippe II, Duke of Orléans.

The gardens were visited and described by John Evelyn, who wrote much about 'the delicious and rarest fruits,' the 'innumerable timber trees in the ground about the seate,' the walks and groves of elms, limes, oaks and other trees, the quarters, walks and parterres, nurseries, kitchen garden, two very noble orangeries, and, 'above all, the canall and fishponds, the one fed with a white, the other with a black running water,' stocked with pike, carp, bream and tench.
