Sir Francis Kynaston or Kinaston (1587–1642) was an English lawyer, courtier, poet and politician who sat in the House of Commons from 1621 to 1622. He is noted for his translation of Geoffrey Chaucer's Troilus and Criseyde into Latin verse (as rime royal, Amorum Troili et Creseidae Libri Quinque, 1639). He also made a Latin translation of Henryson's The Testament of Cresseid.
Kynaston was born at Oteley Park, near Ellesmere, Shropshire, the eldest son of Sir Edward Kynaston and his wife Isabel Bagenall, daughter of Sir Nicholas Bagenall. His father was High Sheriff of Shropshire in 1599. On 11 December 1601 Kynaston matriculated at Oriel College, Oxford. He graduated B.A. from St Mary Hall on 14 June 1604 and M.A. at Oxford on 11 November 1611. He was called to the bar at Lincoln's Inn in 1611. He was knighted by James I at Theobalds on 21 December 1618.
In 1621 Kynaston was elected Member of Parliament for Shropshire. He became esquire of the body to Charles I on the King's accession in 1625.
At court Kynaston was the centre of a literary coterie. In 1635 he founded an academy of learning, called the Musæum Minervæ, for which he obtained a licence under the great seal, a grant of arms, and a common seal; Charles also contributed from the treasury. On 27 February 1636 Prince Charles, the Duke of York, and others visited the museum, and a masque by Kynaston, entitled Corona Minervæ, was performed in their presence. In July of the same year Sir George Peckham bequeathed money to the institution.
