"Billy" Craddock (July 16, 1946 – March 16, 2004) was an American author who published two novels in the early 1970s chronicling psychedelic and biker culture in California in the 1960s.

Craddock has been called one of the seminal chroniclers of the psychedelic period,[2] along with Timothy Leary, Alan Watts and Andrew Weil.

He married Teresa Lynn Thorne on July 27, 1975, and moved to Santa Cruz, California, where he lived until his death in 2004.

[5] In Santa Cruz, Craddock operated a retailer of restored vintage motorcycles with musician Patrick Simmons of the Doobie Brothers.

"[10] Craddock's account of Kesey's Dec 18, 1965 Muir Beach Acid Test was included as a chapter of The Grateful Dead Reader (2000) by David Dodd and Diana Spaulding.

Metro Silicon Valley carried a cover article on Craddock which said "If the Los Gatos native is indeed one of the era's preeminent chroniclers, acknowledgment has lagged.

"Few certifiably clued-in alumni of that scene, it seems, were left with enough cognitive fortitude to compile the definitive tale of the tribe," wrote Wired magazine contributor Steve Silberman about the Be Not Content reissue.
