Giovanni Andrea Bontempi (Perugia, ca. 1624–1 July 1705) was an Italian castrato singer, later composer, historian, music theorist, and assistant kapellmeister to Heinrich Schütz at Dresden from 1657. Born G. A. Angelini, he took the name of his patron. His opera Dafne (composed in collaboration) was performed to open the Opernhaus am Taschenberg in Dresden.
