John Hampden (c. June 1595 – 24 June 1643) was an English landowner and politician whose opposition to arbitrary taxes imposed by Charles I made him a national figure. An ally of Parliamentarian leader John Pym, and cousin to Oliver Cromwell, he was one of the Five Members whose attempted arrest in January 1642 sparked the First English Civil War.
After war began in August 1642, Hampden raised an infantry regiment, and died of wounds received at the Battle of Chalgrove Field on 18 June 1643. His loss was considered a serious blow, largely because he was one of the few Parliamentary leaders able to hold the different factions together.
