Camille du Locle (16 July 1832 – 9 October 1903) was a French theatre director and a librettist. He was born in Orange, France. From 1862 he served as assistant to his father-in-law, Émile Perrin at the Paris Opéra, moving in 1870 to the Opéra-Comique (he was co-director (with Adolphe de Leuven) in the Opéra-Comique).
He is best remembered for mounting the original production of Bizet's Carmen in 1875. His friendship with Ernest Reyer led to him providing libretti for Sigurd and Salammbô. Du Locle was responsible for completing the libretto of Don Carlos after the death of Joseph Méry. He also played a key role in the genesis of Aida in 1869-70. In 1876, a financial dispute arose with Verdi, and Du Locle moved to Capri. He lived in what is called today “Villa Certosella”.
According to Charles Pigot, Du Locle inspired the subject, words and music of Bizet's Djamileh. He was a pall-bearer at Bizet's funeral and made a speech at his interment at Père Lachaise.
Du Locle died in Capri.
