Maurice Étienne Legrand, who published under the pseudonym Franc-Nohain (25 October 1872 – 18 October 1934) was a French librettist and poet. He is best known for his libretti for Maurice Ravel's opera L'heure espagnole and for numerous operettas by Claude Terrasse.
Maurice Étienne Legrand was born in 1872 in Corbigny; his father was an overseer-agent. He attended the Lycée Janson de Sailly. In the late 1880s he contributed poems to the literary magazine Potache-Revue (potache being slang for 'schoolkid'), along with André Gide, Léon Blum, Pierre Louÿs, Maurice Quillot and others. Later, he published in the journal Le Chat noir. He also founded Le Canard sauvage and became the editor of L'Écho de Paris. He also became a lawyer and deputy prefect.
His literary pseudonym Franc-Nohain was derived from the Nohain River, where he had spent many happy hours as a child.
He died in Paris in October 1934, aged 61.
