Greyfriars Church is an evangelical Anglican church, and former Franciscan friary, in the town centre of Reading in the English county of Berkshire. The church forms part of the Church of England's Diocese of Oxford. It is the oldest Franciscan church still in use as a place of worship in the UK, and is said to be the most complete surviving example of Franciscan architecture in England. As a consequence, it has been listed as a Grade I listed building.
