Arthur Goodwin (circa 1593/94 – 16 August 1643)[1] of Upper Winchendon, Buckinghamshire was an English lawyer and politician who sat in the House of Commons at various times between 1621 and 1643.

[2] He was believed to have been born in 1593 or 1594 (being described as 40 years old in his father's will in 1634)[3] He was educated in Oxfordshire at Lord Williams's School, was a law student of the Inner Temple in 1613 and graduated with BA from Magdalen College, Oxford on 10 February 1614.

When open war broke out between Parliament and the King, he gave substantial sums to the Parliamentarian cause, and commanded a cavalry regiment.

In August 1642, he joined Hampden and Bulstrode Whitelocke to capture the Earl of Berkshire, who had been attempting to execute a commission of array in Oxfordshire for the King.

Goodwin was appointed Parliamentary commander-in-chief of Buckinghamshire in January 1643,[4] and made an unsuccessful attempt to seize Brill.
