Giacomo Vaghi (21 November 1901 - 29 April 1978) was an Italian opera singer who had an active international career from 1925-1956. Along with Tancredi Pasero and Ezio Pinza, he was one of the leading operatic basses of his generation. He possessed a rich voice with a dark timbre that drew him particular acclaim in the operas of Giuseppe Verdi. He appears on several complete opera recordings made with EMI Classics and Cetra Records.
