Welterweight is a weight class in combat sports. Originally the term "welterweight" was used only in boxing, but other combat sports like Muay Thai, taekwondo and mixed martial arts also use it for their own weight division system to classify the opponents. In most sports that use it, welterweight is heavier than lightweight but lighter than middleweight.
A welterweight boxer's weight is greater than 63.5 kg (140 lb), but less than 66.7 kg (147 lb).
Henry Armstrong holds the record for the most consecutive title defenses at this division, with 19 defenses of the lineal title.
