Jérôme Leroy is a French-American composer whose work spans television drama, film, and large-scale entertainment productions.

Originally from Paris, Leroy has built a career at the intersection of storytelling and music. His television credits include the 40-episode Chinese drama series The Ideal City for iQiyi, and multiple dramatic television films for Hallmark Channel including An American in Austen, A Paris Proposal, and the Hallmark Hall of Fame production One Christmas Eve. His work extends to action thrillers such as The Throwaways for Sony Crackle and the documentary miniseries Hostages of Lebanon for Planète+.

His film work ranges from intimate dramatic features including the romantic thriller Chi Chi Em Em and the vampire drama Daydreamers, to contributions on major studio productions such as the Universal animated film The Tale of Despereaux and the Lionsgate blockbuster The Hunger Games.

Leroy's command of symphonic music is central to his practice. He has recorded with orchestras at Abbey Road Studios and AIR Studios in London, and on scoring stages in Prague, Budapest, Los Angeles, and beyond. His extensive arranging work includes reimagining John Williams' Star Wars scores for Disneyland's Fire of the Rising Moons, and Marvel Cinematic Universe music for multiple Avengers Campus shows worldwide.

Currently based in Paris, Leroy is the founder of two music production companies—L'air du soir in Paris and Visual Sounds & Music in Los Angeles—and works regularly across the US, Europe, and Asia.
