National Hot Rod Association

The National Hot Rod Association (NHRA) is a governing body which sets rules in drag racing and hosts events all over the United States and Canada. With over 40,000 drivers in its rosters, the NHRA claims to be the largest motorsport sanctioning body in the world.

The association was founded by Wally Parks in 1951 in California to provide a governing body to organize and promote the sport of drag racing. NHRA's first Nationals was held in 1955, in Great Bend, Kansas. The NHRA Mission Foods Drag Racing Series, the national event series which comprises 24 races each year, is the premier series in drag racing that brings together the best drag racers from across North America and the world. The NHRA U.S. Nationals are now held at Lucas Oil Raceway in Brownsburg, Indiana and are officially called the U.S. Nationals. Winners of national events are awarded a trophy statue in honor of founder Wally Parks. The trophy is commonly referred to by its nickname, "The Wally".

Wally Parks, editor of Hot Rod magazine and a dry lakes racer himself, began the National Hot Rod Association to promote "safety, sportsmanship, and fellowship" among hot rodders. The association gained about 25,000 members in its first year; within six years, it had more than 57,000 members.

Hot Rod magazine and NHRA worked together to convince the general public and especially the police that there was a difference between hot-rodders and reckless street racers, sometimes known as "shot rodders". They encouraged the involvement of adults, such as auto shop teachers and garage owners. The NHRA's efforts to defend the image of the hot-rodder included a series of short films such as The Cool Hot Rod (1953) in which a delinquent teen learns that "a reckless kid in an old junker is not a hot-rodder at all. He's a square."

NHRA initiated the 1954 "Drag Safari", a nationwide tour to encourage organized drag racing with an emphasis on safety. Sponsored by Mobil Oil, the Safari crew would meet with law enforcement and local city officials at each stop to explain their program, involve local car clubs, set up sites, and run drag races. Drag Safari would lead to the 1955 US Nationals for drag racing.

Due to the coronavirus pandemic in the United States, the NHRA cancelled its 2020 and 2021 editions of the Drag Racing Series at the Virginia Motorsports Park. Regular scheduling resumed in 2022, with the events taking place in May of that year.

Currently, there are two headquarters offices, one in San Dimas, California, and the other in Brownsburg, Indiana at Lucas Oil Indianapolis Raceway Park. The Mission Foods Drag Racing Series offices are held in Brownsburg.

The NHRA Mission Foods Drag Racing Series is the top division of the NHRA. It consists of four professional classes:
