Jacques Loussier (born 26 October 1934) is a French pianist and composer. He is well known for his jazz interpretations in trio formation of many of Johann Sebastian Bach's works, such as the Goldberg Variations. He is also a licensed pilot and often flew his personal helicopter from his home at Chateau Miraval, in the south of France. This same chateau now belongs to Brad Pitt and Angelina Jolie. Loussier has also been involved with rosé wine production.

For more than six decades, pianist Jacques Loussier has explored where the structure and traditions of classical music intersect with the spontaneous and exploratory nature of jazz. In the early years of his career, his Play Bach Trio focused on developing improvisatory compositions around the works of Johann Sebastian Bach. In more recent years with Telarc and a newly formed trio assembled in the 1980s Loussier expanded his repertoire by taking a similar approach to composers like Debussy, Ravel, Vivaldi, Beethoven and others.
