Jean-Pascal Beintus (born 1966) is a French composer.

Beintus was born in Toulouse. He studied double bass and composition at the conservatories of Nice, Lyon and Paris during the 1980s. When John Eliot Gardiner created the Lyon Opéra Orchestra in 1983, he selected Beintus as a founding double bass player. His first work, Samskara, was for double bass and chamber orchestra.
