The Three Rivers Convention Center is the convention center for the Tri-Cities of south-eastern Washington, United States. It gets its name from the Snake River, Yakima River, and Columbia River, all of which intersect in the general area of the Tri-Cities. It is located in western Kennewick, adjacent to the Toyota Center, and opened in 2004.^[1]

Early proposals for a convention center in the Tri-Cities emerged in the late 1970s, with the three principal cities of the area competing to attract a potential suitor.^[2] The initial plan for the Tri-Cities Coliseum (now Toyota Center) in the 1980s included an adjacent convention center, but it was not realized for several decades.^[3]
