Thomas Belasyse, 1st Earl Fauconberg PC (c. 1627 – 31 December 1700) was an English peer. He supported the Parliamentary cause in the English Civil War, becoming close to Oliver Cromwell and marrying Cromwell's third daughter, Mary. After the Restoration of the monarchy he became a member of the Privy Council to Charles II and was elevated to an earldom by William III.

Belasyse was the only son of Hon. Henry Belasyse, who was the eldest son of Thomas Belasyse, 1st Viscount Fauconberg. Unlike his Royalist father and grandfather, Belasyse supported Parliament in the English Civil War, and subsequently became a strong adherent of Oliver Cromwell, whose third daughter, Mary, he married in 1657. His father died in 1647 and he succeeded his grandfather to the viscounty of Fauconberg in the Bishopric of Durham in 1652.

Belasyse again became a Royalist at the Restoration of the monarchy, and was appointed a member of the Privy Council of England by Charles II and Captain of the Guard (in which office he succeeded his uncle Lord Belasyse). He also served as English ambassador in Venice. He was Lord Lieutenant of the North Riding of Yorkshire (1660–1692). He was one of the noblemen who joined in inviting William of Orange to England, and was by that king created Earl Fauconberg, in the Peerage of England, on 9 April 1689.
