University constituencies existed from 1603 until 1950 to allow a University to be represented in the United Kingdom Parliament.

King James I of England, on ascending the English throne, brought to the English Parliament a practice which had been used in the Scottish Parliament of allowing the Universities to elect members. The King believed that the Universities were often affected by the decisions of Parliament and ought therefore to have representation in it.

Cambridge University and Oxford University were therefore given two seats each from 1603. The voters were the graduates of the university, whether they were resident or not, who had the vote for their University in addition to any other vote that they might have. After the Act of Union 1800 with Ireland, the University of Dublin (Trinity College) was allowed two members from 1801.

The University of London was enfranchised with one member in 1868, along with four Scottish Universities in two groups each electing one member. The list of Universities was further enlarged in 1918, including the Queen's University, Belfast. This also received four seats in the Stormont Parliament that was established in 1920. At this point the Scottish Universities switched to all electing three members jointly (see Combined Scottish Universities (constituency)).

The Labour government in 1930 attempted to abolish the University constituencies but was defeated in the House of Commons. Although the members for the University Constituencies were usually Conservatives, in the later years Independent candidates began to win many of the seats. In 1948 the Labour government abolished the University constituencies along with all other examples of plural voting.

The Members for the University constituencies include many notable statesmen: William Pitt the Younger was MP for Cambridge University from 1784 to his death, and William Gladstone was MP for Oxford University at one point. In their last years Ramsay MacDonald was MP for Scottish Universities after losing his seat in the 1935 general election. Many criticised this as he had previously sought to abolish the seats when Labour Prime Minister and many now felt the seats were being used to provide a failed politician with a seat he could not find elsewhere.

The Queen's University, Belfast survived in the Northern Ireland Parliament until it was abolished in 1968 by the Electoral Law Act (Northern Ireland) 1968 (1968 c. 20, Act of the Stormont Parliament). This was part of a series of measures by the-then Northern Ireland Prime Minister Terrance O'Neill to reform elements of the election franchise and deal with many long standing civil rights grievances.

In the Irish Free State, university constituencies of the Seanad Éireann (Irish Free State) were abolished by the Electoral (University Constituencies) Act, 1936 of June 29, 1936. Later under the Constitution of Ireland 1937 six members of Seanad Éireann were elected by graduates of two universities then in existence, the University Panel.

Some other former countries of the British Empire, such as India, had university constituencies. The Indian Constitution, however, provided that these University Constituencies no longer have a force in law. Nonetheless, the President of India has the authority to appoint not more than twelve scientists, artists, or other persons who have special knowledge in similar fields, to the Rajya Sabha.
