Henri Duparc (January 21, 1848 – February 12, 1933) was a French composer of the late Romantic period.

He was born in Paris. He studied piano with César Franck at the Jesuit College of Vaugirard and became one of his first composition pupils. In 1871, he joined with Saint-Saëns and Romain Bussine to found the Société Nationale de Musique.

Because of mental illness, he ceased composing in 1885 and destroyed most of his works, leaving only 14 songs which are still extremely popular. His texts are based on poets such as Baudelaire, Gautier, and Goethe.

He spent most of his later life in Switzerland and died in Mont-de-Marsan, France.
