Toño Rosario, born Antonio Rosario in 1955 in Higüey, La Altagracia, is one of the most charismatic and enduring figures in Dominican merengue. A member of the extended Rosario family that gave Dominican music Los Hermanos Rosario, he developed a solo career that established him as a significant artist in his own right, distinct from the family band's commercial juggernaut.

Known for his joyful stage presence, his wit, and his ability to connect with audiences of all ages, Toño Rosario became a beloved entertainer who embodied the celebratory spirit at the heart of merengue. His recordings blended humor and romance in a way that was distinctly his own, and he developed a series of hits that audiences in the Dominican Republic and its diaspora know by heart.

Toño Rosario has remained active across decades of shifting musical fashions, sustained by his genuine love of performance and the loyalty of fans who have grown up with his music.
