William de Reyny was a thirteenth-century feudal landholder whose Somerset interests included Aisholt and Aley in Over Stowey. He appears in the context of the Curci baronial inheritance and associated knight's fees.

The source does not establish whether he held the whole manor in demesne or held it as a mesne tenant of a superior lord.
