The National Stock Car Racing Association (NSRA/NSCRA) was a sanctioning body for stock car racing that operated in the Southeastern United States during the late 1940s and early 1950s. Competing against several other sanctioning bodies, including NASCAR, NSCRA was considered to be the most significant challenge to NASCAR's dominance of the sport; however it proved incapable of competing with the larger sanction, and closed down midway through the 1951 racing season.
