The Tri-Cities are a group of three closely tied cities (Richland, Kennewick, and Pasco) located at the confluence of the Yakima, Snake, and Columbia rivers in the semi-arid region of Southeastern Washington. A fourth neighboring city, West Richland, and the nearby CDP of Burbank (which is not part of the metropolitan area) are generally included as part of the Tri-City area and region, as are a handful of unincorporated communities. Each city borders either another city or one of the area's rivers, making the Tri-Cities seem like one uninterrupted mid-sized city. The cities function as the center of the Tri-Cities metropolitan area.

The combined population of the three cities was 193,567 at the 2010 Census. As of April 1, 2016, the Washington State Office of Financial Management, Forecasting Division estimates the cities as having a combined population of 232,740 The Tri-Cities Airport located in Pasco provides the region with commercial and private air service. Pasco is the seat of Franklin County, while the other cities are located in Benton County. Both counties are officially defined as the Kennewick-Richland, WA Metropolitan Statistical Area.

In 2010, Kiplinger rated the Tri-Cities among the Top 10 best places to raise a family, and CNN/Money ranked the Tri-Cities one of the top 10 best bets for gains in housing value, due to its relatively stable economic conditions since the early 2000s.
