Daniel Lentz (born March 10, 1942, Latrobe, Pennsylvania) is a classical electronic music composer.

Lentz achieved notability as a musician while a student at Brandeis University, when he was awarded a fellowship in composition at Tanglewood in the summer of 1966. This was followed by a Fulbright Fellowship in Electronic Music in 1967–68, which was completed in Stockholm, Sweden. He then became a visiting lecturer at the University of California, Santa Barbara in 1968. In 1970 he focused more on composing and performing. At this time he also formed a music ensemble, the California Time Machine, which toured North America and Europe.
