The Flash is the name of several fictional characters appearing in comic books published by DC Comics. Created by writer Gardner Fox and artist Harry Lampert, the original Flash first appeared in Flash Comics #1 (January 1940).^[1] Nicknamed the "Scarlet Speedster", all incarnations of the Flash possess "super speed", which includes the ability to run and move extremely fast, use superhuman reflexes, and seemingly violate certain laws of physics.

Thus far, four different characters – each of whom somehow gained the power of "super-speed" – have assumed the mantle of the Flash in DC's history: college athlete Jay Garrick (1940–1951, 1961-present), forensic scientist Barry Allen (1956–1985, 2008–present), Barry's nephew Wally West (1986–2011, 2016–present), and Barry's grandson Bart Allen (2006–2007). Each incarnation of the Flash has been a key member of at least one of DC's premier teams: the Justice Society of America, the Justice League, and the Teen Titans.

The Flash is one of DC Comics' most popular characters and has been integral to the publisher's many reality-changing "crisis" storylines over the years. The original meeting of the Golden Age Flash Jay Garrick and Silver Age Flash Barry Allen in "Flash of Two Worlds" (1961) introduced the Multiverse storytelling concept to DC readers, which would become the basis for many DC stories in the years to come. Like his Justice League colleagues Superman and Batman, the Flash has a distinctive cast of adversaries, including the various Rogues (unique among DC supervillains for their code of honor) and the various psychopathic "speedsters" who go by the name Reverse-Flash. Other supporting characters in Flash stories include Barry's wife Iris West, Wally's wife Linda Park, friendly fellow speedster Max Mercury, and Central City police department members David Singh and Patty Spivot.

A staple of the comic book DC Universe, the Flash has been adapted to numerous DC films, video games, animated series, and live-action television shows. In live action, Barry Allen has been portrayed by Rod Haase for the 1979 television special Legends of the Superheroes, John Wesley Shipp and Grant Gustin in the 1990The Flash series and the 2014 The Flash series, respectively, as well as by Ezra Miller in the DC Extended Universe series of films, beginning with Batman vs Superman: Dawn of Justice (2016). Shipp also portrays a version of Jay Garrick in the 2014 The Flash series. The various incarnations of the Flash also feature in animated series such as Superman: The Animated Series, Justice League, Batman: The Brave and the Bold and Young Justice, as well as the DC Universe Origina
