John Henry Creach (May 28, 1917 – February 22, 1994), better known as Papa John Creach, was an American blues violinist who also played classical, jazz, R&B, pop and acid rock music. Early in his career, he performed as a journeyman musician with Louis Armstrong, Fats Waller, Stuff Smith, Charlie Christian, Big Joe Turner, T-Bone Walker, Nat King Cole and Roy Milton.

Following his rediscovery by drummer Joey Covington in 1967, he fronted a variety of bands (including Zulu and Midnight Sun) in addition to playing with Jefferson Airplane, Hot Tuna, Jefferson Starship, the San Francisco All-Stars (1979–1984), Dinosaurs (1982–1989) and Steve Taylor.

Creach recorded a number of solo albums and guested at several Grateful Dead and Charlie Daniels Bandconcerts. He was a regular guest at the early annual Volunteer Jams, hosted by Charlie Daniels, which exposed him to a new audience that was receptive to fiddle players.

Creach was born in Beaver Falls, Pennsylvania, near the border of Ohio. As a child, he was introduced to the violin by an uncle, and he received both tutoring in the instrument and conservatory training. Creach and his family moved to Chicago in 1935.
