St William's College is a Mediaeval building in York in England, originally built to provide accommodation for priests attached to chantry chapels at nearby York Minster. It is a Grade I listed building.
The college was founded in 1460 by George Neville and the Earl of Warwick to house twenty-three priests and a provost. It was named after St William of York.
In 1465, work started on the present building. This courtyard structure may incorporate parts of two earlier houses. It included a great hall to the north, with a chapel to its east.
