Joseph Roumanille (Occitan: Josèp Romanilha, August 8, 1818 – May 24, 1891) was a Provençal poet. He was born at Saint-Rémy-de-Provence (Bouches-du-Rhône), and is commonly known in southern France as the father of the Félibrige, for he first conceived the idea of raising his regional language to the dignity of a literary language.
Joseph Roumanille was the son of Jean-Denis Roumanille and Pierrette Piquet. He studied at the nearby collège (junior highschool) of Tarascon (Bouches-du-Rhône) from 1834. After working as clerc de notaire in the same town from 1836 to 1839, Roumanille published his first verses in the Écho du Rhône. He then worked as a teacher in Nyons (Drôme), and later at the Dupuy collège in Avignon. When Roumanille was a teacher at Avignon, he discovered the genius of Frédéric Mistral, one of his pupils, and together they began what later became the Félibrean movement.
He married Rose-Anaïs Gras, sister of Provençal poet and novelist Félix Gras.
In 1888, Roumanille succeeded Frédéric Mistral to become 2nd Capoulie of the Félibrige, an association devoted to the Provençal language and Provençal literature. He died in Avignon in the morning of May 24, 1891. His funeral was held on May 26 in Avignon, and he was buried in Saint-Rémy-de-Provence, in the same grave as his parents.
