约翰·邓尼斯·普罗富莫，CBE（John Dennis Profumo，1915年1月30日－2006年3月9日），别名为杰克·普罗富莫，是英国政治家，也是1963年普罗富莫事件的中心人物，该事件对当时麦美伦的保守党政府构成很大打击，更导致了保守党政府在一年后垮台。普罗富莫晚年热心于在伦敦的一所慈善团体，汤恩比服务所（Toynbee Hall）中当义工，并凭他个人的政治技巧和人脉关系，为该慈善团体筹得大笔善款。在1975年，他获由OBE（军事）晋升为CBE，以志其公益贡献。

他的妻子是女演员瓦莱莉娅·霍布森（Valerie Hobson）。

Brigadier John Dennis Profumo, CBE (/prəˈfjuːmoʊ/ prə-FEW-moh; 30 January 1915 – 9 March 2006), informally known as Jack Profumo, was a British politician. The Profumo family is of Italian origin, and John Profumo held the title of 5th Baron Profumo in the nobility of the Kingdom of Sardinia. Although Profumo held an increasingly responsible series of political posts in the 1950s, his career ended after he had a sexual relationship with the 19-year-old model Christine Keeler in 1963. The scandal, which became known as the Profumo affair, led to his resignation and withdrawal from politics, and it may have helped to topple the Conservative government of Harold Macmillan.
