Green Valley Raceway, former motorsport racing track in Smithfield, Texas, US

Green Valley Raceway was a motorsport racing facility in Smithfield, Texas, opened in 1960 on Bill McClure's farm and operated for over 20 years. The site featured a quarter-mile drag strip and a longer road course starting at about 1.6 miles (2.6 km), later extended to 2.1 miles (3.4 km), accommodating drag racing, road racing, and other competition formats.

Green Valley Raceway opened in 1960 on Bill McClure's North Texas dairy farm in Smithfield, with its first full season in 1961 drawing 125,000 spectators. The original 1.6-mile road course, whose start-finish straight doubled as a drag strip, was lengthened to 2.1 miles in 1966. It hosted Trans-Am and SCCA races and a Can-Am round in 1984 before closing in 1986; the track has since been demolished for housing, and Green Valley Elementary School now stands on the site.

The nickname 'The Track that Milk Built' came from its site on Bill McClure's North Texas dairy farm. The venue drew 125,000 spectators in its first full season in 1961, and its start-finish straight doubled as a drag strip for NHRA and AHRA events.

Green Valley Raceway stood on Bill McClure's dairy farm in Smithfield, Texas, within the Dallas–Fort Worth metroplex. The site has since been demolished and replaced by housing developments; Green Valley Elementary School now occupies part of the former track grounds.

The track is gone, but Green Valley Elementary School stands on its site, and its perfect-attendance trophy is made from a piece of the demolished raceway. The school keeps a physical remnant of the circuit where Trans-Am and Can-Am cars once ran.
