The Benelux Union (Dutch: Benelux Unie; French: Union Benelux; German: Benelux-Union; Luxembourgish: Benelux-Unioun West Frisian: Benelúks Uny) or Benelux is a politico-economic union, alliance and formal international intergovernmental cooperation of three neighbouring states in Western Europe: Belgium, the Netherlands, and Luxembourg. The name is a syllabic abbreviation formed from the initial syllable of each country's name and was first used to name the customs agreement that initiated the union (signed in 1944). It is now used more generally to refer to the geographic, economic, and cultural grouping of the three countries.

The Benelux is an economically dynamic and densely populated region, with 5.6% of the European population (29.55 million residents) and 7.9% of the joint EU GDP (€36,000/resident) on 1.7% of the whole surface of the EU. In 2015, 37% of the total number of EU cross-border workers worked in the Benelux; 35,000 Belgian residents work in Luxembourg, while 37,000 others cross the border to work in the Netherlands each day. In addition, 12,000 Dutch and close to a thousand Luxembourg residents work in Belgium.

The main institutions of the Union are the Committee of Ministers, the Council of the Union, the General Secretariat, the Interparliamentary Consultative Council and the Benelux Court of Justice. The Benelux Office for Intellectual Property (BOIP) covers the same land but is not part of the Benelux Union. However, as from June 2018, the Benelux Court of Justice has the competence to judge BOIP's decisions in appeal.

The Benelux General Secretariat is located in Brussels. It is the central platform of the Benelux Union cooperation. It handles the secretariat of the Committee of Ministers, the Council of Benelux Union and the sundry committees and working parties. The General Secretariat provides day-to-day support for the Benelux cooperation on the substantive, procedural, diplomatic and logistical levels. The Secretary-General is Ariadne Petridis from Belgium and there are two deputies: Deputy Secretary-General Liesje Schreinemacher from the Netherlands and Deputy Secretary-General Tom Köller from Luxembourg.

The presidency of the Benelux is held in turn by the three countries for a period of one year. The Netherlands hold the presidency for 2026.

About 80 percent of the population of the Benelux countries speaks Dutch as a native language, around 20 percent speaks French, and approximately 1 percent speaks Luxembourgish as a first language. A small minority, under 1 percent, are native German speakers.
