Nino Martini (7 August 1902 — 10 December 1976) was an Italian operatic tenor and actor. He began his career as an opera singer in Italy before moving to the United States to pursue an acting career in films. He appeared in several Hollywood movies during the 1930s and 1940s while simultaneously working as a leading tenor at the Metropolitan Opera in New York City.

Martini possessed a warm lyric tenor voice that had a wide range and considerable amount of coloratura facility. He sang mostly within the Italian repertoire that encompassed the bel canto literature of Rossini, Donizetti, and Bellini, the grand operas of Giuseppe Verdi, and the verismo operas of Giacomo Puccini.
