Gabriel Bacquier (17 May 1924 – 13 May 2020) was a French operatic baritone. One of the leading baritones of the 20th century and particularly associated with the French and Italian repertoires, he was considered a fine singing actor equally at home in dramatic or comic roles and gave regular song recitals.

He was a long-term member of the Opéra-Comique and the Paris Opera, but forged a long career internationally at leading opera houses in Europe and the U.S. His large discography spans five decades, and he was considered as “the ambassador of French song”.
