Ruggero Raimondi (born 3 October 1941) is an Italian bass-baritone opera singer who has also appeared in motion pictures.

Ruggero Raimondi was born in Bologna, Italy, during World War II. His voice matured early into its adult timbre, and at the age of 15, he auditioned for conductor Francesco Molinari-Pradelli, who encouraged him to pursue an operatic career. He began vocal studies with Ettore Campogalliani, and was accepted at age 16 as a student at the Giuseppe Verdi Conservatory in Milan. He then continued his studies in Rome, under the guidance of Teresa Pediconi and Armando Piervenanzi.
