Marvin Delph (born September 15, 1956[1]) is an American former basketball player, who experienced his greatest success at the college level.

In high school, Delph led the Conway Wampus Cats to two state basketball championships, in 1973 and 1974.

Known for his outside shooting and remarkable leaping ability, Delph was a member of the University of Arkansas Razorbacks NCAA Final Four team in 1978.

Along with Sidney Moncrief and Ron Brewer, he was labeled as one of the "Triplets", a trio of Arkansas-born, similarly sized players who led Arkansas basketball through a tremendous resurgence after years of mediocre play.

Unlike his fellow Triplets, Delph never played in the NBA, despite several attempts.
