Euston Hall is a country house, with park by William Kent and Capability Brown, outside Bury St Edmunds, Suffolk, in England.

Euston first appears in the Domesday Book in 1087 as a manor belonging to Bury St. Edmunds Abbey. In 1578, Elizabeth I stayed at the manor hall with the Rookwood family on her way to Norwich. The Estate, in near ruin, was purchased in 1666 by Henry Bennet, Earl of Arlington and Secretary of State to the newly-restored King, Charles II. He constructed a grand house in the French style, built around a central court with large pavilions on each corner. Charles II paid the first of several visits to Euston in 1671. John Evelyn, the diarist, was amongst the large court that accompanied the King.

The property was inherited in 1685 by his daughter and son-in-law, the first Duke and Duchess of Grafton. In about 1750 their son, the Second Duke, decided to re-model the house and employed Matthew Brettingham, who succeeded William Kent in designing Holkham Hall in Norfolk. The domes at Euston were replaced by the low pyramid roofs seen today, and part of the house was refaced. In 1902, a disastrous fire destroyed the south and west wings and the fine Verrio ceilings. The house was soon rebuilt on the same plan, but later the south wing, and most of the west wing, were pulled down by the Tenth Duke in 1952.

The old park was designed by the diarist John Evelyn, a noted landscape gardener and an expert on trees, with a canal, straight rides and avenues. His designs for Euston included the walk through the pleasure grounds which can still be enjoyed today. The whole park and river layout was designed by William Kent in 1738, and is considered one of his great works. His temple and entrance archway survive. Lancelot Brown worked here, intermittently, from 1776 to 1784 to complete the project. Euston's watermill was built in the 1670s by Sir Samuel Morland for irrigation and grinding corn. In 1731, it was redesigned by William Kent to resemble a church, and in 1859 an iron waterwheel was added by Charles Burrell . The Temple (not open to the public) is an unusual octagonal folly designed by William Kent in 1746. It was his last work. It has a magnificent octagonal banqueting hall rising to a dome.

Euston Hall has a fine art collection, but one Canaletto deserves special mention. According to the Sporting Magazine, February 1793: "About the year 1735 he [The 2nd Duke of Grafton] kept foxhounds at Croydon and went to London very early on the days he hunted. The old Duke used to complain bitterly of the interruption he met with (in crossing the Thames at Westminster) for the delay and inattention of the ferry man, etc., by which he often lost several hours of a fine morning before he arrived in Croydon. To remove this inconvenience he projected a bridge at Westminster, and brought a bill into Parliament for its erection, which was completed in the year 1748". For many years there hung at Euston Hall a contemporary Caneletto of the bridge being built.
