Sean Francis Hughes (8 May 1946 – 24 June 1990) was a British history teacher and Labour politician. He was the local successor to Sir Harold Wilson as a Member of Parliament, and served as a whip and a spokesman on defence issues for his party. Respected for his Parliamentary abilities and able to use his historical knowledge in Parliamentary speeches, he played a role in changing Labour's defence policy from unilateral nuclear disarmament to a multilateral approach. His Parliamentary career was cut short by his early death from cancer.
