Duncan Dhu was a Spanish group created in San Sebastián, Spain in 1984. Its original members were Mikel Erentxun (former singer in "Aristogatos"), Diego Vasallo and Juan Ramón Viles (former members of "Los Dalton").

The group's style was based on an acoustic and simple pop-rock with a touch of rockabilly in great contrast with the more radical rock played in the area at the time. After being hired by 'Grabaciones Accidentales, S.A.' they contributed with two songs (Mi Amor and Bésame Mucho) to the new bands compilation La única alternativa (The Only Alternative).
