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.
The first known instance of the term is from 1831, meaning "heavyweight horseman," later "boxer or wrestler of a certain weight" by 1896. This sense comes from earlier "welter" "heavyweight horseman or boxer" from 1804, possibly from "welt", meaning "to beat severely", from c. 15th century.
A welterweight boxer's weight is greater than 63.5 kg (140 lb), but no more than 66.7 kg (147 lb).
