Flyweight is a weight class in combat sports.

Boxing

Flyweight is a class in boxing which includes fighters weighing up to and including 51 kg (112 lb) for a title fight.

Professional boxing

The flyweight division was the last of boxing's eight traditional weight classes to be established. Before 1909, anyone below featherweight was considered a bantamweight, regardless of how small the boxer. In 1911, the organization that eventually became the British Boxing Board of Control held a match that crowned Sid Smith as the first flyweight champion of the world. Jimmy Wilde, who reigned from 1916 to 1923, was the first fighter recognized both in Britain and the United States as a flyweight champion.{{cite book | last = Mullan | first = Harry | title = Boxing: The Definitive Illustrated Guide to World Boxing | publisher = Carlton Books | year = 1996 | location = London, England | isbn = 0-7858-0641-5 | page = 186}}
