Georges Sébastian (August 17, 1903 – April 12, 1989) was a French conductor of Hungarian birth, particularly associated with Wagner and the post-romantic repertory (Bruckner, Mahler, Richard Strauss).
Born György Sebestyén, he studied first the piano and violin in his native Budapest, before turning to composition.
In 1921, he was engaged as répétiteur at the Munich State Opera, where he worked with Bruno Walter and became his assistant conductor the following year.
Upon his return in Europe, he conducted at the opera houses of Hamburg and Leipzig, before becoming first conductor at the Städtische Oper Berlin (1927–30).
