Charles-Henri de Blainville (1711–1769 [or after 1771]) was a French composer, cellist, pedagogue and music theorist.
The birthplace of Charles-Henri de Blainville remains uncertain.
Blainville entered the service of the Marquise de Villeroy.
In 1751, he made himself known by affirming that there existed a "third mode" between minor and major.
He wrote two theoretical works: L'Esprit de l'art musical ou réflexions sur la musique and L'Histoire générale, critique et philosophie de la musique.
