John Vance (10 December 1808 – 21 September 1875) was a Conservative MP for Dublin City from 1852 until his defeat in 1865. He was later elected unopposed for Armagh City and represented the constituency from 30 June 1867 until his death. In the 1847 General Election Vance was unsuccessful in his attempts to be elected for Canterbury. In 1853 the Canterbury Bribery Commission found his agent guilty of bribery.
