James Nyx Jr. (May 3, 1914 – July 16, 1998), sometimes credited as James Nyx, was an American songwriter for the Motown label. He co-wrote "Inner City Blues (Make Me Wanna Holler)" which became a #9 hit for Marvin Gaye in 1971. Nyx was born in Indianapolis, Indiana, but moved to Detroit in the 1930s, where he married twice and raised a family of eight children. He supported them through jobs requiring menial labor. At one time he was a resident of the Brewster-Douglass Housing Projects, where notable figures such as Diana Ross grew up.
