The Long-Thibaud-Crespin Competition (Concours Long-Thibaud-Crespin) is a prestigious international music competition held in Paris, France, focusing on piano, violin, and, in some editions, opera singing. Founded in 1943 by pianist Marguerite Long and violinist Jacques Thibaud, and later joined by soprano Régine Crespin, it aims to discover and promote outstanding young soloists at the start of their professional careers. Participation is open to advanced young musicians from around the world who meet the age and repertoire requirements for each instrument category; these age limits typically place it beyond the usual range for most high school students, favoring conservatory-level or early-career performers. Finalists perform in major Parisian venues before an international jury and public audience. Winners receive international exposure, concert engagements, and career support, making the competition a significant springboard for professional classical music careers.
