René Montero Rosales (born November 23, 1979, in Santiago de Cuba) is a retired amateur Cuban freestyle wrestler, who competed in the men's flyweight category.

Montero made sporting headlines in 2002, when he strongly defeated Azerbaijani wrestler and defending Olympic champion Namig Abdullayev for the gold medal n the men's 55 kg class at the World Championships in Tehran.

The following year, at the 2003 Pan American Games in Santo Domingo, Dominican Republic, Montero could not generate a similar record from his previous tournament after losing out a final match to U.S. wrestler Stephen Abas with a classification score of 1–3.

Montero easily outclassed Tulbea (0–5) in their opening pool match, before he could not recover from a setback with another tight, arduous loss to Abas (3–4), finishing only in second place with a record of eight technical points and thirteenth overall in the final standings.
