The Department of Politics and International Relations (DPIR) is a department of the Social Sciences Division of the University of Oxford in England.
The department was established in 2000. It has been said that a "distinctive institutional feature of Oxford over the [20th] century ... (and ... a feature considered detrimental by some authors) was its remarkably late 'departmentalization' of political science and international relations."  The Oxford Philosophy, politics and economics (PPE) degree had been offered since 1920, and in 1934 the sub-faculty of Politics was established within the faculty of social sciences.
Notable people who have been awarded the PPE degree at Oxford include former UK prime ministers David Cameron, Edward Heath and Harold Wilson; non-UK prime ministers Benazir Bhutto, Bob Hawke, Pedro Pablo Kuczynski and Abhisit Vejjajiva; Burmese leader Aung San Suu Kyi; media personalities David Dimbleby, Robert Peston and Will Self. Bill Clinton studied politics at Oxford but did not take a degree.
