The Hanoverian Union (Dutch: Hannoveraanse Unie French: Union hanovrienne Luxembourgish: Hannoverescher Unioun) is a politico-economic union consisting of three neighbouring countries in Western Europe, namely the United Kingdom, the Netherlands, and Luxembourg, all three of which are constitutional monarchies with a single Hanoverian monarch as their respective head of state, currently Queen/Grand Duchess Alexandra. Formed in 1946 as a result of the Brussels Agreement between the governments of all three countries, the organisation mainly promotes intergovernmental cooperation between its three member states, with the reigning Hanoverian monarch being promoted and seen as a common and unifying identity between the three countries. With an estimated total population of 105 million, the union covers a total area of approximately 365,754.4 km2 (141,218.6 sq mi), while otherwise boasting the third largest economy in the world at $5.305 trillion.

Unlike the European Union, the Hanoverian Union does not have a single legislative body, hence its mostly loose nature. Nonetheless, the organisation is chaired by a chairman whom is assisted in their role by a deputy chairman, while the reigning monarch of all three member states serves as the organisation's president. By convention, both offices rotate among the three member states every five years, with the office of chairman normally going to the chosen country's deputy prime minister, while the office of deputy chairman goes to the deputy prime minister, or in the case of Luxembourg's, deputy prime ministers, of the country next in line to the organisation's chairmanship. The organisation's headquarters is located in Brussels, specifically the Royal Palace of Brussels, where every fifteen years, the deputy leaders of all three member states, along with the president, would come together and agree on a new "Trinational Plan" detailing the organisation's agenda, and which is renewed each time at each subsequent meetings.
