Buckingham Chantry Chapel is a 15th-century chapel located in Buckingham, Buckinghamshire, England, and now a National Trust property.
The chapel is the oldest building in Buckingham and is noted in particular for its Norman doorway.
It was restored by Sir George Gilbert Scott in 1875. At that time, the chapel was being used by the Royal Latin School. In 1907 the school expanded and so moved to new buildings on Chandos Road.
