St Michael and All Angels is a Grade I listed church on the estate of the Duke of Beaufort in the village of Great Badminton, Gloucestershire, England. Attached to the Duke of Beaufort's residence, Badminton House, it is an active Anglican parish church in the diocese of Gloucester. Although within the grounds of the Badminton Estate, the church is owned, and its upkeep met, by the Badminton's Parochial Church Council, rather than the Ducal estate. There is a smaller church of the same name in the neighbouring hamlet of Little Badminton.
The current church was built in 1785 by Charles Evans in the style of St Martin-in-the-Fields, London, in miniature, but with a plain tower. The medieval predecessor church, which was then demolished, lay slightly further to the West.
The nave of the church has a tunnel-vault with ornamental panelled plasterwork and classical four-bay arcades and aisles with four small saucer domes. The chancel and apse were added in 1875 to accommodate the elaborate monument to Henry Somerset, 1st Duke of Beaufort by Grinling Gibbons. The 1st Duke was buried alongside his ancestors in the Beaufort Chapel in St George's Chapel, Windsor, but the monument was moved to Badminton in 1878.
Within the church, the pulpit and box pews date from 1785, while the organ case, choir stalls, reredos and communion rail were made by Temple Moore in 1908. The eight windows for the aisles, four on each side, have stained glass of 1846-1847 by Thomas Willement with heraldic designs, blue borders, and badges in the yellow of the Beaufort livery.
