TriCity

TriCity, often styled as TriCity or Tri-City, is a toponym used to describe a metropolitan area, district, or branding that encompasses three adjacent or closely linked cities or municipalities. The concept emphasizes shared economic, transportation, or cultural ties that arise from the proximity of three urban centers. The term is widely used in English-speaking regions and appears in planning documents, tourism materials, and local branding.

Geographic usage in the United States includes two well-known regions: the Tri-Cities in Washington state—Pasco, Kennewick, and Richland—and the Tri-Cities region of northeast Tennessee and southwest Virginia—Bristol, Johnson City, and Kingsport. Both function as multi-city economic hubs with coordinated services and infrastructure, though each retains separate municipal governments.

Beyond geographic regions, TriCity is used in branding and organization names, including corporate entities, shopping developments, sports teams, or events that aim to signal collaboration among three communities.
