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