Sir Beauchamp St John (17 March 1594 – 1667) was an English politician who sat in the House of Commons variously between 1621 and 1653.
[1] He was admitted fellow commoner at Queens' College, Cambridge on 9 March 1609/10, and was conferred an MA in 1612/3, on the occasion of the King's visit.
[7][8] In April 1640, St John was elected MP for Bedford in the Short Parliament.
He was re-elected for Bedford for the Long Parliament in November 1640, where he was active at least in 1643 and remained in support of the parliamentary cause.
