Pierre Marie François de Sales Baillot (1 October 1771 – 15 September 1842) was a French violinist and composer born in Passy. He studied the violin under Giovanni Battista Viotti and taught at the Paris Conservatoire together with Pierre Rode (also a pupil of Viotti) and Rodolphe Kreutzer, who wrote the conservatoire's official violin method (published in the early 19th century). He was sole author of the instructional L'art du violon (1834). Baillot's teachings had a profound influence on technical and musical development in an age in which virtuosity was openly encouraged. He was leader of the Paris Opéra, gave solo recitals and was a notable performer of chamber music. He died in Paris in 1842.
