Sébastien de Brossard was a French music theorist, composer and collector.
In 1687, Brossard was named a vicar at the Strasbourg Cathedral. He remained there until 1698. He founded an Académie de Musique at Strasbourg in 1687 and arranged Lully's Alceste for performance there. It was during the decade he spent in Strasbourg that he acquired the bulk of his music library, which has since become legendary. A collection of 157 sonatas acquired by Brossard bears the name Codex Rost, after the Cantor at Baden-Baden, Franz Rost (1640-1688). It is sometimes the only source of works by certain German and Italian composers of the 17th century.
