Tri-City Raceway is a 0.500 mi (0.805 km) tri-oval short track in West Richland, Washington. The facility has hosted a variety of events since its opening in 1968, including NASCAR and CARS Tour West events. Tri-City Raceway is owned by the city of West Richland and is operated by the Friends of Red Mountain Event Center and the West Richland Police Department.

Tri-City Raceway opened in 1968 under the ownership of the Western Sintering Company. Within the first 15 years of the track's existence, the track faced constant financial troubles and disputes with drivers despite numerous managers. In 1982, a group of four businessmen acquired the facility's lease and revitalized the track in the following years. In 1999, the facility was sold to Paul Alderman, and after a period of high-turnover with its managers, Alderman closed the facility for auto racing after 2004. The track was acquired in 2008 by the Port of Kennewick, who planned to turn the facility into a wine-related business. However, the plans ultimately fell through, and the track was sold to the city of West Richland in 2019. With the city's purchase, multiple organizations leased out the track, including the Friends of Red Mountain Event Center, who organized the return of auto racing in 2021.

Tri-City Raceway is measured at 0.5 mi (0.80 km). Unlike most short tracks, Tri-City Raceway is shaped in the form of a tri-oval, with three turns instead of the usual four.

The track is located in West Richland, Washington, and served by Washington State Route 224. On track property, a 5-acre (2.0 ha) police station owned by the West Richland Police Department was constructed and completed in 2021.

On January 11, 1968, president of the Western Sintering Company, John Rector, announced plans to build a 0.5 mi (0.80 km) tri-oval racing facility named "Tri-City Raceways". Initial plans for the facility included the tri-oval, a dirt motocross track within the tri-oval's infield, and 4,000 grandstand seats. In addition, newly-appointed track manager Jerry Wagner also announced near-future master plans, which included plans to construct a dragstrip and a sports car track layout. Groundbreaking on Tri-City Raceway occurred on March 11, and the first events were held at the track on April 28 on the tri-oval. The first events on the track's motocross circuit were held two weeks after on May 12. On August 17, the first NASCAR-sanctioned race was held at the facility's tri-oval, with Ray Elder winning a NASCAR Pacific Coast Late Model Division event. According to the Tri-City Herald, the entire facility, including land and construction costs, costed $250,000 (adjusted for inflation, $2,314,593).

In 1969, Tri-City Raceway underwent a renovation project, which included the installation of new bleacher seats, a new press box, and improved spectator amenities. Two years later, Wagner was replaced as manager and operator of Tri-City by Raceway Industries, Inc., led by president George Cantrell. As part of Cantrell's tenure, the pit area was moved from outside the eastern portion of the track to the infield of the track, which was achieved by the removal of the motocross track. In a 1999 interview, Rector described the motocross track as "a disaster", having lost money in every event it hosted. Months into his tenure, Cantrell faced a boycott from the track's jalopy racing division drivers due to purse money disputes. The following year, A&P Sports, headed by racing driver Bill Amick, took over operational control of Tri-City Raceway. In later interviews, Amick stated that the jalopy driver boycott was a primary reason for his investment in the track. During Amick's tenure, he reported that A&P Sports lost money on operating the facility due to purse increases and renovations, leading to the eventual cutting of sportsman racing for the rest of 1972 starting in August.

By the start of 1973, A&P Sports opted out of their lease due to numerous disagreements with the organization and drivers, with sportsman racer Larry Pryor taking over operations in January. Like Amick, Pryor also stated that he lost money operating the track, and he gave up operating control to Steve Dickmann in 1976. After three years under Dickmann's operational control, local businesspeople Doug and Karen McGaughey took over operations in 1979. After facing declining car counts for races and driver disputes due to a lack of communication between the drivers and the McGaugheys, they gave up their control to former racing driver Joe Bonner in October 1979. Although Bonner was reported by the Herald to have improved the financial situation of the facility in May 1980 with increased attendance in comparison to 1979, by the end of the year, the track came under criticism from drivers due to inconsistent rules.

After the track experienced a financially "mediocre" season in 1981, Bonner gave up operating control to a group of four businessmen consisting of Gene Wagner, Wayne Walden, Jerry Harmon, and Jack Goodell for 1982 on November 1, 1981. By 1985, Herald writer Hec Hancock wrote that the operators, now consisting of Walden, Goodell, and Tom Cissell, were "winning an uphill battle to put the track in the black" with rising attendance figures and a new $60,000 scoreboard being installed within the year. In December 1998, after Walden's lease expired, the Herald reported the sale of Tri-City Raceway to Paul Alderman, a Ellensburg car dealer. Within the first year of Alderman's ownership, several renovations were made to the facility, including the installation of an improved lighting system, flattening the infield, adding power and water stations for pit stalls, and completing the track's irrigation system. In 2001, Dennis Williams became the promoter of Tri-City Raceway; he left in June 2002 due to financial problems. Five months after Williams' departure, Alderman hired Chris Lewandoski as the track's general manager. By April 2003, multiple renovations were made, including the construction of a 1⁄4 mi (0.40 km) track within the tri-oval and additional lighting.
