William Hiseland (6 August 1620 – 7 February 1732/33), sometimes spelt William Hasland or Haseland, was a long-lived English and later British soldier and reputed supercentenarian. In 1709, at the age of eighty-nine, he fought at the Battle of Malplaquet and was believed to be the oldest soldier on the field. He lived to become the last survivor of the English Civil Wars, which he had served in from 1642 to 1651.
