The year 2026 was the 15th year in the history of Ultimate Warrior Challenge Mexico, a mixed martial arts promotion based in Mexico.
UWC Mexico 57: Miranda vs. Chávez was a mixed martial arts event held by Ultimate Warrior Challenge Mexico on March 22, 2026, at the Arena Tecate in Tijuana, Mexico.
UWC Mexico 57 was originally scheduled for June 29, 2025, but the event was canceled due to a change of venue. In February 2026, UWC announced that the event would take place on March 22 at Arena Tecate, marking the first time the venue has hosted a UWC event.
Before the event's cancellation in 2025, it had been announced that Miguel Villegas and Christian Zapién would face off in the main event. With the 2026 announcement, Villegas was replaced by Israeli Ilay Bazilay to face Zapién in a UWC Lightweight Championship bout. However, the fight suffered another setback when Zapién suffered an injury that took him off the card, being replaced by Marco Antonio Elpidio. But again the fight was canceled, and what was supposed to be the co-main event was moved to the main event.
The main event featured a catchweight fight between Ricardo Chávez Villaseñor and Alexis Miranda, who, as mentioned, were announced of the co-main event.
Meanwhile, the bantamweight fight between Johnny Muñoz Jr. and Alfredo Larios was moved to the co-main event.
