Libero De Luca (13 March 1913 – 1998) was a Swiss tenor of Italian descent particularly associated with the French repertory.
De Luca was born in Kreuzlingen, Switzerland, and studied voice at the Zurich Conservatory with Alfredo Cairati.
After winning a first prize at an international voice competition in Geneva, in 1941, he made his professional debut the following year at the Solothurn Municipal Theatre.
In 1949, he made his debut at both the Opéra-Comique and the Palais Garnier, where he established himself as a lead tenor in the French repertoire.
Libero De Luca was fluent in German, French and Italian, and excelled in all three repertoires in lyric roles.
