Sir Thomas Kitson (1485 – 11 September 1540) was a wealthy English merchant, Sheriff of London, and builder of Hengrave Hall in Suffolk.

He served as Sheriff of London in 1533–34,[3] and was knighted on 30 May 1533 at the coronation of Anne Boleyn, (an honour not conferred on his co-sheriff, William Forman).

[3] One of Kitson's apprentices was Sir Rowland Hill,[3] who was Lord Mayor of London in 1549 and is associated with the Geneva Bible's publication.

He also purchased properties in the counties of Devon, Dorset and Somerset, and in 1521 acquired from Edward Stafford, 3rd Duke of Buckingham, for £2340, the manors of Hengrave in Suffolk and Colston Bassett in Nottinghamshire.

[3] On the Duke's attainder and execution in the following year, Kitson was for a time deprived of the estates, but they were restored to him, confirmed by an Act of Parliament of 1524.
