Sir John Bernard, 2nd Baronet (November 1630 – 25 June 1679) was an English politician who sat in the House of Commons between 1654 and 1660.
Bernard was educated at Huntingdon and was admitted at Middle Temple on 21 January 1645 and at Christ's College, Cambridge on 12 April 1646.
As lord of the manor, he made himself highly unpopular, using his legal knowledge to eject small freeholders from their property.
Bernard died at the age of 48 and was buried at Brampton church, Northamptonshire, where he is commemorated on a marble monument, against the south wall.
Bernard married firstly Elizabeth St John, daughter of Oliver St John, Lord Chief Justice of the Common Pleas, by whom he had one son, Robert, his successor, and eight daughters, of whom Joanna, the fifth, married the Rev.
