Reynaldo Hahn de Echenagucia (9 August 1874 – 28 January 1947) was a Venezuelan-born French composer, conductor, music critic, and singer. Known for his more than 100 songs, Hahn spent most of his life in Paris, where he became a prominent member of fin de siècle French society.

Hahn was a prolific composer, creating vocal works, orchestral pieces, chamber music, and piano works. His music was neglected after his death, but from the late 20th century onward, there has been a resurgence of interest in his works, leading to frequent performances and recordings of his compositions. Hahn's early years were influenced by his upbringing in a multilingual household and his musical education at the Paris Conservatoire, where he studied with renowned composers and musicians such as Jules Massenet and Camille Saint-Saëns. His talent was recognized early on with the success of his mélodie "Si mes vers avaient des ailes," which gained praise from critics and was dedicated to his sister Maria. Hahn
