Air racing is a motorsport that involves airplanes competing over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time.
The first heavier-than-air air race was held on May 23, 1909 - the Prix de Lagatinerie, at the Port-Aviation airport south of Paris, France. Four pilots entered the race, two started and nobody completed the full race distance though this was not unexpected as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange who covered slightly more than half of the ten 1.2-kilometre laps was declared the winner.
Some other minor events were held before the Grande Semaine d'Aviation de la Champagne in August 22–29, 1909 at Reims, France. This was the first major international flying event, drawing the most important aircraft makers and pilots of the era, as well as celebrities and royalty. The premier event — the first Gordon Bennett Trophy competition — was won by Glenn Curtiss, who beat second place finisher Louis Blériot by five seconds. Curtiss was named "Champion Air Racer of the World".
In the years before the First World War popular interest in aviation led to a large number of air races in Europe, including the 1911 Circuit of Europe race, the Daily Mail Circuit of Britain Air Race and the Aerial Derby.
In 1913 the first Schneider Trophy seaplane race was held. When the competition was resumed after the war it was significant in advancing aeroplane design, particularly in the fields of aerodynamics and engine design, and would show its results in the best fighters of World War II.
On October 19, 1919, the Army Transcontinental Air Race began along a 2700 mile route from Long Island, New York to San Francisco, California and back which would see widespread carnage including 7 fatalities (2 en route to the race) and of the 48 aircraft that started, 33 would complete the double crossing of the continent.
In 1921, the United States instituted the National Air Meets, which became the National Air Races in 1924. In 1929, the Women's Air Derby became a part of the National Air Races circuit. The National Air Races lasted until 1949. The Cleveland Air Races was another important event. In 1947, an All-Woman Transcontinental Air Race dubbed the "Powder Puff Derby" was established, running until 1977.
In 1964, Bill Stead, a Nevada rancher, pilot, and unlimited hydroplane racing champion, organized the first Reno Air Races at a small dirt strip called the Sky Ranch, located between Sparks, Nevada, and Pyramid Lake. The National Championship Air Races were soon moved to the Reno Stead Airport and have been held there every September since 1966. The five-day event attracts around 200,000 people, and includes racing around courses marked out by pylons for six classes of aircraft: Unlimited, Formula One, Sport Biplane, AT-6, Sport and Jet. It also features civil airshow acts, military flight demonstrations, and a large static aircraft display. Other promoters have run pylon racing events across the USA and Canada, including races in Las Vegas, NV in 1965, Lancaster, CA in 1965 and 1966, Mojave, California in 1970-71, and 1973–79; at Cape May, NJ in 1971, San Diego, CA in 1971, Miami, FL in 1973 and 1979, Moose Jaw, Saskatchewan in 1984; Hamilton Field, California, in 1988; at Dallas, TX in 1990, in Denver, CO in 1990 and 1992, in Kansas City in 1993, in Phoenix, Arizona in 1994 and 1995; and in Tunica, Mississippi in 2005. Numerous other venues across the United States, Canada, and Mexico have also hosted events featuring the smaller Formula One and Biplane classes.
In 1970, American Formula One racing was exported to Europe (Great Britain, and then to France), where almost as many races have been held as in the U.S.A. Also in 1970, the California 1000 Air Race started at the Mojave Airport with a 66 lap unlimited air race that featured a Douglas DC-7 with one aircraft completing the circuit.
Red Bull has created a series called the Red Bull Air Race World Championship in which competitors fly individually between pairs of pylons, while performing prescribed maneuvers. Usually held over water near large cities, the sport has attracted large crowds and renewed media interest in air racing.
Aero GP has multiple aircraft racing together around pylons, and is based in Europe where it has held an air race each year since 2005.
Powered paragliding or Paramotor races have been organized with the first occurring on 4 September 2010 in an airfield in Montauban, Southern France. These are parasails powered by small two-stroke engines and allow a much smaller race where the audience can see the pilots as they carry out their maneuvers.
Sky Challenge Air Race was announced in July 2011 and combines real racing aircraft which are tracked with GPS with a virtual environment visible from the cockpit through a Head-up display while flying, and to the viewers on the ground with a flight simulator that they may use to join in the race.

Restricting aircraft to a specific type or design creates a competition that focuses on pilot skill. Air racing events such as the Reno air races, incorporate multiple classes or aircraft. These may be defined by the race organizer, or by a sanctioned group. Some air races are limited to a single class. Classes used at the Reno races are as follows:
|Class||First Race||Primary Description||Course||Sanctioned|
|T-6 Air Racing||1946||T-6/Harvard/SNJ with a P&W R-1340-AN-1 engine||Pylon|

Cultural depictions 
- Set in the 1930s, the movie Porco Rosso briefly touches on the early days of air racing.
- "The Rocketeer" comic books feature air racing prominently as the story is set during the 1930s.
- The 1965 film Those Magnificent Men in Their Flying Machines depicts a £10,000-prize air race between London and Paris. The film takes place in 1910 and utilizes many authentic reproductions of airplanes from that era.
