Ashton Court (grid reference ST553723) is a mansion house and estate to the west of Bristol in England. Although the estate lies mainly in North Somerset, it is owned by the City of Bristol. The estate has been a venue for a variety of leisure activities, including the now-defunct Ashton Court festival, Bristol International Kite Festival and the Bristol International Balloon Fiesta. On the 18th September 2011 the estate played host to a 12 hour softball match for a cancer charity.

The core of the house was built in the 15th century, but it was enlarged and adapted over the centuries by the Smyth family, who bought the estate in 1545. The south facade and the wing incorrectly attributed to Inigo Jones date from about 1633 and were extended eastwards in the 19th century. The house became derelict after the last of the Smyths died in 1946; it was taken over by the City in 1959, and restoration has been an ongoing process since then. The facilities of the house are now rented out for business conferences, parties and weddings.
