Lillian Bilocca (26 May 1929 – 3 August 1988) was a British fisheries worker and campaigner for improved safety in the fishing fleet as leader of the "headscarf revolutionaries" – a group of fishermen's family members. Spurred into action by the Hull triple trawler tragedy of 1968 which claimed 58 lives, she led a direct action campaign to prevent undermanned trawlers from putting to sea and gathered 10,000 signatures for a petition (the Fishermen's Charter) to Harold Wilson's government to strengthen safety legislation. She threatened to picket Wilson's house if he did not take action. Government ministers later implemented all of the measures outlined in the charter.
