John Whistler (c. 1580 – 1647) was an English lawyer and politician who sat in the House of Commons at various times between 1624 and 1644.
He matriculated at Trinity College, Oxford on 14 October 1597 aged 17 and was awarded BA on 17 February 1601.
[2] In that same year he was also made a freeman of the city, served as a fee'd counsel and was appointed a Justice of the Peace for Oxford.
He was re-elected MP for Oxford in 1625, 1626 and 1628 and sat until 1629 when King Charles decided to rule without parliament for eleven years.
[1] He supported the King and attended the Oxford Parliament in 1644, which caused him to be disabled from sitting in the House of Commons, probably in January 1644.
