Thomas Howard, 3rd Earl of Berkshire (14 November 1619 – 12 April 1706) was an English peer, styled Hon.
In 1661, after the English Restoration, he was rewarded with the sinecure office of Clerk of the Markets of the Household.
He was succeeded by his great-nephew Henry Howard, who then united the earldoms of Suffolk and Berkshire.
He was reputed to have fathered at least one illegitimate child, Moll Davies, who became an actress and mistress to Charles II, bearing him a daughter, Lady Mary Tudor who married the Earl of Derwentwater.
Moll Davis was born around 1648 in Westminster and was said by Samuel Pepys, the famous diarist, to be "a bastard of Colonel Howard, my Lord Barkeshire" - probably meaning Thomas Howard, third Earl of Berkshire.
