William Perkins or Parkyns (c.1400-c.1449) was an English landowner and Member of Parliament.
Perkins was the first of his family to arrive in Berkshire, where he held the manor of Ufton Robert.
In his early years, William was a bailiff for Prince Humphrey, Duke of Gloucester.
In 1427, and several years later, William Perkins served as Escheator for the counties of Berkshire and Oxfordshire.
This union created the modern day village of Ufton and allowed his children to hold the patronage of the combined living.
