Joan Ambrosio Dalza (fl. 1508) was an Italian lutenist and composer of the Renaissance era.

His surviving works comprise the fourth volume of Ottaviano Petrucci's influential series of lute music publications, Intabolatura de lauto libro quarto (Venice, 1508). Dalza is referred to as milanese in the preface, so it must be assumed he was either born in Milan, or worked there, or both.
