Carlos Roberto Cuadras Quiroa (born August 24, 1988) is a Mexican former professional boxer who held the WBC super flyweight title from 2014 to 2016. As an amateur he won a gold medal in the bantamweight division at the 2007 Pan American Games.

Cuadras won the gold medal at the 2007 PanAmerican Games by beating local James Pereira and winning the final against Dominican southpaw Claudio Marrero 15-11.

At the 2007 World Amateur Boxing Championships he lost to Joe Murray: 19-28.

In February 2010, Cuadras knocked out Oswaldo Rodriguez to win the WBC Youth Intercontinental Super Flyweight Championship at the Poliforum Zamná in Mérida, Yucatán.

Cuadras is managed by his father Rosario Cuadras, and promoted by Japan's Teiken Promotions. He has trained with Jose Luis Bueno and others at Bueno's Gym or his own gym in Mexico, often training under Sendai Tanaka's instruction in Japan.

In September 2011, Cuadras competed for the vacant WBC Continental Americas Super Flyweight Title against Johnny García at the Foro Polanco in Mexico City. He was knocked down with García's left hook in the first round. However, after his barrage in the second round, he landed a left to the liver and a right to the jaw to floor García twice, and captured the title with the stoppage victory.

Cuadras went up a weight division and knocked out Javier Franco in the fifth round after flooring him to be crowned the WBC United States (USNBC) Bantamweight Champion at the Playa Mamitas in Playa del Carmen on June 16, 2012.

On November 13, 2014 Cuadras was scheduled to defend his title against Sonny Boy Jaro, but Jaro was replaced with Marvin Mabait due to having visa problems.^{[citation needed]}
