Jules-Jean-Paul Fort (1 February 1872 – 20 April 1960) was a French poet associated with the Symbolist movement. At the age of 18, reacting against the Naturalistic theatre, Fort founded the Théâtre d'Art (1890–93). He also founded and edited the literary reviews Livre d'Art with Alfred Jarry and Vers et Prose (1905–14) with poet Guillaume Apollinaire, which published the work of Paul Valéry and other important Symbolist writers. Fort is notable for his enormous volume of poetry, having published more than thirty volumes of ballads and, according to Amy Lowell, for creating the polyphonic prose form in his 'Ballades francaises'.
