Westboro Speedway, also known as Westboro Sports Stadium,^[1] was a one-quarter mile (0.40 km) banked and paved oval race track located in Westborough, Massachusetts, that operated from 1947 through 1985. It featured various types of racing including super-modified and midget cars.^[2]

The track was built by Allied Sports Association, a group of five former World War II soldiers, on land that had been part of a farm owned by the DeBoer family.^[3] Construction cost was reported as $100,000 (equivalent to $1,364,531 in 2023).^[4] The first race at the speedway was held on August 5, 1947.^[1]

Notable drivers to race at the speedway included Joe Sostilio in the track's inaugural season,^[5] and Geoff Bodine and Ron Bouchard in the mid-1970s.^[6] In 1982, the track hosted two races on the NASCAR North Tour, one in June and one in September.^[7] The final race held at the speedway was contested on September 14, 1985.^[8]

In addition to its use as a race track, the facility was also a venue for musical performances. Boston-based Aerosmith played at the speedway on August 18, 1974,^[9][10] and the Gregg Allman Band played at the speedway in 1983.^[3]

After the track closed and was razed, a strip mall branded as Speedway Plaza was constructed on the site.^[8][11]
