Sir Thomas Chicheley (25 March 1614 – 1 February 1699) of Wimpole Hall, Cambridgeshire was a politician in England in the seventeenth century who fell from favour in the reign of James II.

He was born the eldest surviving son of Thomas Chicheley (1578–1616) of Wimpole and was related to Henry Chichele, Archbishop of Canterbury and founder of All Souls College, Oxford.

However, being a strong Royalist, he was "disabled from sitting" (in other words expelled) soon after the outbreak of the Civil War.

The same year he became Chancellor of the Duchy of Lancaster, but was ejected from office and expelled from the Privy Council on 2 March 1687 by James II.

[2] According to Pepys, Chicheley lived extravagantly in London, and this was probably the reason that he was forced to sell his Wimpole estate to Sir John Cutler thirteen years before his death.
