John of Gaunt's Palace was a late 14th-century merchant's house which stood in the lower part of Lincoln High Street, opposite the St Mary Guildhall.

The palace was initially built by a member of the wealthy Sutton family of Lincoln merchants in the latter years of the 14th century, on land immediately to the north of St Andrew's church.

There was also a possible lodgings block to the north of the main street front range, which had the arms of John of Gaunt along with other heraldic shields shown above the doors.

A drawing by Samuel Hieronymus Grimm shows a building described as the Old Hospital abutting on to the hall range with its two fine late medieval windows.

The hospital building should date from around 1500, and the lozenge-shaped terminals to the doorway and the sunken panels to the spandrels find a very close parallel with the Chancery, in Minster Yard, Lincoln.
