Terence Allan Crawford (born September 28, 1987) is an American professional boxer. He has held multiple world championships in three weight classes, including the WBO welterweight title since 2018. Previously he held the WBO and Ring magazine lightweight titles from 2014 to 2015; and the unified WBA (Super), WBC, IBF, WBO and Ring light welterweight titles between 2015 and 2017. In August 2017, Crawford had a short reign as the undisputed light welterweight champion, prior to moving up to welterweight. He was the first undisputed champion at light welterweight since Kostya Tszyu in 2004. Crawford also became the first male boxer to simultaneously hold all four major world titles in boxing (WBA, WBC, IBF and WBO) since Jermain Taylor in 2005, and as of June 2022 is one of only eight male boxers in history to do so.
