Sir Thomas Urswick (c.1415–1479), also referred to as Urswyk or Urswyck, was an English lawyer who became recorder of London and Chief Baron of the Exchequer.
He was one of the leading citizens of London who admitted Edward IV into the city in 1471, which led to the imprisonment and death of Henry VI.
He was probably from a north country family, born about 1415, the son of Sir Thomas Urswick of Badsworth, and his wife Joan.
A group of leading citizens with Yorkist sympathies, including Urswick, advised the crowd to go home, and allowed Edward IV to enter the city.
Urswick then played a prominent part in the defeat of the attack by Thomas Fauconberg on London in May, and was knighted in June 1471.
