Gene Clark, born Harold Eugene Clark (November 17, 1944 – May 24, 1991) was an American singer-songwriter, and one of the founding members of the folk-rock group The Byrds.

Gene Clark is best remembered for being The Byrds' main songwriter between 1964 and early 1966. He created a large catalogue of music in several genres but failed to achieve solo commercial success. Clark was one of the earliest exponents of psychedelic rock, baroque pop, newgrass, country rock and alternative country.
