Tricity, or Tri-City (Polish: Trójmiasto; Polish pronunciation: [trujˈmʲastɔ], Kashubian: Trzëgard; Kashubian pronunciation: [tʂəɡart]; German: Dreistadt), is an urban area in Pomeranian Voivodeship, Poland, consisting of three contiguous coastal cities in Pomerelia forming a row on the coastline of the Gdańsk Bay, Baltic Sea, namely the cities of Gdańsk, Gdynia, and Sopot, along with other cities and towns in their vicinity. In 2021, the three core cities were inhabited by 749,786 people, while the Tricity together with its metropolitan area had a combined population of between 1 and 1.5 million, depending on the definition of the boundaries of the latter.
The designation has been used informally or semi-formally only. A strategic cooperation declaration, the Tricity Charter (Polish: Karta Trójmiasta), was signed by the three city mayors on 28 March 2007. The only incorporated common management authority in the Tricity metro is the Gdańsk Bay Public Transport Metropolitan Union (Polish: Metropolitalny Związek Komunikacyjny Zatoki Gdańskiej) which is, despite the name, an inter-municipal union and not a metropolitan one.
