Abraham Elieser Adolph Schönberg, known as Al Shean, was a comedian and vaudeville performer. Other sources give his birth name variously as Adolf Schönberg, Albert Schönberg, or Alfred Schönberg. He is most remembered for being half of the vaudeville team Gallagher and Shean, and as the uncle of the Marx Brothers.

Gallagher & Shean was a highly successful musical comedy double act in vaudeville and on Broadway in the 1910s and 1920s, consisting of Ed Gallagher (1873–1929) and Al Shean (1868–1949); Shean was the maternal uncle of the Marx Brothers.
