Junior welterweight (also called super lightweight or light-welterweight) sits at a sweet spot: fast enough for high-volume wars, powerful enough for highlight-reel finishes. Ranking the best ever at 140 isn’t just about who had the prettiest highlight—it's about dominance at the weight, championship hardware, and signature wins that defined eras.
1) Julio César Chávez (Record: 107–6–2)

Chávez is the 140-pound standard for sustained greatness: a three-division icon who held the WBC light welterweight title twice (1989–1996) and also captured the IBF belt (1990–1991). His defining junior welter moment is the unforgettable unification with unbeaten Meldrick Taylor—“Thunder Meets Lightning”—where Chávez poured on pressure and scored a dramatic late stoppage to unify the WBC and IBF titles.
2) Aaron Pryor (Record: 39–1)
“The Hawk” was a nightmare at 140: relentless pace, huge engine, and a mean finishing instinct. Pryor was a two-time light welterweight world champion (WBA from 1980–1983, IBF from 1984–1985) and also held The Ring title during his peak. His career-defining stretch was the Alexis Argüello rivalry—two iconic wins that cemented Pryor as the division’s most ferocious pressure fighter of his era.
3) Kostya Tszyu (Record: 31–2–1 NC)
Tszyu’s résumé screams “complete champion.” He became the division’s undisputed king in the three-belt era and held the lineal championship from 2001–2005, pairing elite timing with fight-ending power. His signature moment: the unification clash with Zab Judah—“The Fight to Unite”—where Tszyu blew Judah off his feet to claim the WBA (Super), WBC and IBF titles in one night.
4) Antonio Cervantes “Kid Pambelé” (Record: 67–12–1)
Cervantes was a globe-trotting, long-reigning champion who made 140 pounds feel like home. He held the WBA and The Ring light welterweight titles twice between 1972 and 1980, stacking defenses across multiple continents. Key moments include his title-winning KO of Alfonso “Peppermint” Frazer (1972), his stoppage of Nicolino Locche (a marquee defense), and the historic loss to a 17-year-old Wilfred Benítez—boxing’s youngest-ever world champion.
5) Carlos Ortiz (Record: 61–7–1)
Ortiz was a pioneering two-division great who became a junior welterweight world champion in the division’s early modern era. He won the vacant NYSAC/NBA light welterweight titles by stopping Kenny Lane at Madison Square Garden in 1959—one of the signature “firsts” in Puerto Rican boxing history. Ortiz later added a legendary lightweight run, but his 140-pound championship accomplishment and skill level make him a must on any all-time list.
6) Nicolino Locche (Record: 117–4–14)
Locche is the division’s cult hero—and one of boxing’s purest defensive artists. Nicknamed “El Intocable” (The Untouchable), he held the world junior welterweight title from 1968 to 1972, winning rounds with subtle movement, shoulder rolls, and the kind of reflexes opponents couldn’t solve. His title reign and style still get referenced any time fans debate the greatest “hit-and-not-get-hit” operators at 140.
7) Terence Crawford (Record: 42–0)
Crawford’s 140-pound peak was short—but historically loud. He became the undisputed light welterweight champion by knocking out Julius Indongo in 2017, a bout that put the WBA (Super), WBC, IBF, WBO and The Ring titles on the line. That achievement made him the division’s first undisputed champ of the four-belt era and kicked off a run that later built one of the modern sport’s strongest pound-for-pound cases.
8) Josh Taylor (Record: 19–3)
Taylor’s prime at 140 delivered a rare feat: undisputed status in the four-belt era. His defining night was the 2021 win over José Ramírez in Las Vegas, where Taylor dropped Ramírez twice and won a decision to claim the WBA (Super), WBC, IBF, WBO and Ring titles. He wasn’t just collecting belts—he was beating top-level, prime contenders to get them.
9) Wilfred Benítez (Record: 53–8–1)
Benítez makes the list for one of the most jaw-dropping 140-pound achievements ever: at 17 years old, he outboxed Antonio Cervantes to win the lineal and WBA light welterweight championship, becoming the youngest world champion in boxing history. He defended the title three times before moving up, and while his greatest work spans multiple weights, that junior welter breakthrough remains one of the division’s most iconic moments.
