John Henry Creach (May 28, 1917 – February 22, 1994), better known as Papa John Creach, was an American blues violinist, who has also played classical, jazz, be-bop, R&B, pop and acid rock music. Early in his career, he performed as a journeyman musician with such luminaries as 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), The Dinosaurs (1982–1989) and Steve Taylor.

Creach recorded a number of solo albums and guested at several Grateful Dead and Charlie Daniels Band concerts. 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 at Beaver Falls, Pennsylvania. As a child, he was introduced to the violin by an uncle, and he received both tutoring in the instrument and conservatory training. He began playing violin in Chicago bars after his family moved there in 1935, and also did some symphonic work when he was in his early 20s, which was unusual for a black musician at the time. At one point, he joined a local cabaret trio called the Chocolate Music Bars, and toured the Midwest with them.
