Gaston Gosselin (b. 1999) is an American composer whose music is a playful yet thoughtful exploration of outward joy and inner reflection. His work has been commissioned and performed by groups such as the Eureka Ensemble, Kendall Square Orchestra, South Florida Youth Symphony, Lès Art Nouveau Chalumeaux, as well as the University of Cincinnati Cello Society for the 2023 Ascent International Chamber Music Festival.

Gaston's compositions have earned him recognition and awards, including the Emil and Ruth Beyer Composition Award from the National Federation of Music Clubs, the Molly Garrett & June Fooshee Collegiate Grant from the Music Club of Hollywood Florida, and Mu Phi Epsilon from whom he received the Ruth Dean Morris Scholarship and the Original Composition Award in Divisions I, II, and III. He has also been a finalist for the Morton Gould ASCAP Awards. He has served as a fellow with notable festivals such as the Mostly Modern Festival (USA), Mostly Modern Festival (Netherlands), Lake George Music Festival, Iceberg Institute, Cortona Sessions for New Music, and Conducting Institute.

He is associate director of the South Florida Clarinet Choir, a summer festival that fosters collaboration among student musicians, professionals, and educators in exploring ever-developing new literature for the clarinet choir. This summer, SFCC celebrates its 10th anniversary, welcoming a collaboration with select members of the President's Own clarinet section. 

Gaston resides in Boston, MA, where he works as an artistic fellow with the Eureka Ensemble. He holds a BM in Music Composition from the University of North Texas, where he studied with Sungji Hong, Kirstin Soriano, and Bruce Broughton.
