Sylvius Leopold Weiss (12 October 1687 – 16 October 1750) was a German composer and lutenist.

Born in Grottkau near Breslau, the son of Johann Jacob Weiss, also a lutenist, Weiss was one of the most important and most prolific composers of lute music in history and one of the best-known and most technically accomplished lutenists of his day.

In later life, Weiss became a friend of Wilhelm Friedemann Bach and met J.S. Bach through him. Bach and Weiss were said to have competed in improvisation.
