Antonio Superchi (11 January 1816 – 5 July 1893) was an Italian operatic baritone who had an active international career from 1838–1858. He appeared at most of the major opera houses in Italy and Spain, and at Her Majesty's Theatre in London. The Times reviewed the quality of his voice in 1847 (22 April): "It is impossible for a singer to be more free than Superchi from this defect of his predecessor (Luciano Fornasari, who never surmounted his tremulousness). His notes are as firm as possible, and his flow of song is in the highest degree smooth and even".
