This is a list of the fighters currently signed to contract in the UFC's welterweight division. All fighters have been organized by their number of appearances in the UFC. Fighters with the same number of appearances are organized by number of wins, fighters with the same record are organized alphabetically. Each fight record has four categories: wins, losses, draws, and no-contests (NC). All fight records in this article are displayed in that order, with fights resulting in a no-contest listed in parentheses.

World Extreme Cagefighting (WEC) was purchased by Zuffa in 2006 and officially merged under the UFC brand on January 1, 2011. In April 2011 Zuffa purchased the Strikeforce organization, and officially folded it into the UFC in January 2013. All former WEC and Strikeforce fighters are marked with an asterisk * and have had their ZUFFA record listed in place of their UFC record, starting with WEC 25 and Strikeforce Challengers 15. These records have been, and will be, continued as former WEC and Strikeforce fighters move on in the UFC.

Fighter weight-class changes are noted with either an upward arrow or a downward arrow next to their names. This applies to fighters who have publicly announced a weight change but have yet to fight, as well as those who, like Anderson Silva, are fighting out of their natural weight class and then immediately returning to their previous one.

"TOTT" stands for "Tale of the Tape", designating the nationality used for each fighter during a UFC broadcast.
