Sir Francis Darcy (died 29 November 1641) was an English soldier and politician who sat in the House of Commons at various times between 1601 and 1629.
He became a captain in Colonel Morgan’s regiment under the Earl of Leicester and served in the Netherlands in 1585.
He settled at Isleworth in 1592 and became a J.P. by 1596 and a commissioner for musters in 1598, "being a gentleman of great experience in martial affairs".
He was elected MP for Middlesex again in 1628 and sat until 1629 when King Charles decided to rule without parliament and did so for eleven years.
[1] Darcy died in 1641 and was buried with his wife at Isleworth, where an elaborate monument was erected.
