Producers chose 26-year-old Ismael Cruz Cordova, who will play the role of "Mondo".
Cordova won the role, beating out hundreds of hopefuls who auditioned to be the shows first new Hispanic character in years.
He says it's a dream come true that's brought him full circle to American television.
"My first experience with television, watching TV, was in Puerto Rico," Cordova said. "I only spoke Spanish. I learned how to speak English watching this show."
Cordova says his goal as the newest member of the show is to teach children the Spanish language.
He'll make his debut when Sesame Street's 44th season premieres next September.
