Mini flyweight, also known as strawweight, minimumweight or super atomweight, is a weight class in combat sports.
In boxing, the undisputed champion of a weight class is the boxer who simultaneously holds world titles from all major organizations recognized by each other and the International Boxing Hall of Fame. There are currently four major sanctioning bodies: WBA, WBC, WBO, and IBF. There were many undisputed champions before the number of major sanctioning bodies recognizing each other increased to four in 2007, but there have been only 19 boxers to hold all four titles simultaneously.
In combat sports where champions are determined by challenge, the lineal championship in a weight class represents an intangible world title first held by the victor of a bout between top contenders in the division. A fighter who defeats the reigning champion in a match within the same weight class becomes the next lineal champion. In professional boxing, the lineal champion is informally known as "the man who beat the man."
In boxing, a weight class is a measurement weight range for boxers. The lower limit of a weight class is equal to the upper weight limit of the class below it. The top class, with no upper limit, is called heavyweight in professional boxing and super heavyweight in amateur boxing. A boxing match is usually scheduled for a fixed weight class, and each boxer's weight must not exceed the upper limit. Although professional boxers may fight above their weight class, an amateur boxer's weight must not fall below the lower limit. A nonstandard weight limit is called a catchweight.
