Tri-City Raceway is a 0.500 mi (0.805 km) asphalt oval race track located in West Richland, Washington. Tri-City Raceway is currently being featured in the ARCA Menards Series West division of NASCAR. The track was built to represent and named after the three nearby cities to the racetrack. The track is the only 0.500 mi (0.805 km) mile paved trioval in North America.

The track was opened in 1968 and quickly became an icon in the Eastern Washington area. The track was closed in 2004 and reopened in 2021 to begin hosting primarily NASCAR and other stock car events.

The track hosted various NASCAR West, Northwest, Pacific, and Late Model series from 1968 to 2004 when the track closed. Following the track reopening in 2021, the track would host locally sanctioned events and northwest late model touring series as well as opening back into NASCAR in 2024 with the ARCA Menards Series West.

The track was named after the Tri-Cities in Washington.

The track exclusively hosts a local sports car series called the Sand and Sage Sports Car Club. The club provides sports car racing during the summer and some autocross schooling.
