Miles Crispin (died 1107), also known as Miles or Milo of Wallingford, was a wealthy Norman landowner, particularly associated with Wallingford Castle in Berkshire (now Oxfordshire). The Domesday Book records Miles as a major landowner with holdings in Berkshire, Buckinghamshire, Oxfordshire, Surrey, Wiltshire and two other neighbouring counties as well as being Tenant-in-chief in a lengthy list of places. During the Rebellion of 1088, Miles Crispin was a supporter of William II, and was in the army that later arrested William de Saint-Calais.
