Jean Doyen (8 March 1907 – 21 April 1982) was a French classical pianist, pedagogue and composer.
Born in Paris, Doyen graduated from the Conservatoire de Paris as pianist in 1922. He began learning the instrument with Sophie Chéné (teacher of Blanche Selva), then studied with Louis Diémer (1919) and finally with Marguerite Long. In 1924, he made his solo debut with the Concerts Colonne. He also participated in Jacques Ibert's ballet Les Rencontres, at the Opera Garnier.
In 1926 he worked at the Radiodiffusion Française, but at the same time he returned to the Conservatoire in counterpoint class with Georges Caussade and music composition with Paul Vidal and Henri Büsser.
From 1941 to 1977, he was professor of piano at the Conservatoire de Paris, succeeding Marguerite Long. Among his pupils were İdil Biret, Roger Boutry, Philippe Entremont, Marie-Thérèse Fourneau, Claude Kahn, André Krust, Arthur Moreira Lima, Bernard Job, Dominique Merlet and Chantal Riou.
