Groningen (/ˈɡroʊnɪŋən/ GROH-ning-ən, UK also /ˈɡrɒnɪŋən/ GRON-ing-ən; Dutch: [ˈxɣoʊnɪŋə(n)] ; Gronings: Grunn or Grunnen [ˈχrʏnn̩]) is the capital city and main municipality of Groningen province in the Netherlands. Dubbed the "capital of the north", Groningen is the largest city as well as the economic and cultural centre of the northern part of the country; as of January 2025, it had 244,807 inhabitants, making it the sixth largest city/municipality in the Netherlands and the second largest outside the Randstad. The Groningen metropolitan area has a population of about half a million inhabitants.
Groningen was established more than 980 years ago but never gained city rights. Due to its relatively isolated location from the then successive Dutch centres of power (Utrecht, The Hague, Brussels), Groningen was historically reliant on itself and nearby regions. As a Hanseatic city, it was part of the North German trade network, but later it mainly became a regional market centre. At the height of its power in the 15th century, Groningen could be considered an independent city-state and it remained autonomous until the late 18th century, when it was incorporated into the Napoleonic Batavian Republic.
