John Payne Guerin (October 31, 1939 – January 5, 2004) was an American percussionist. He was a proponent of the jazz-rock style.

Guerin was born in Hawaii and raised in San Diego. As a young drummer, he began performing with Buddy DeFranco in 1960. In the late 1960s, he moved to Los Angeles where his drum work was utilized by artists including Frank Sinatra, The Beach Boys, George Harrison, Frank Zappa, The Animals, Joni Mitchell, Them, Thelonious Monk, Lou Rawls, Ray Conniff, George Shearing, Peggy Lee, Ella Fitzgerald, Linda Ronstadt, Nelson Riddle and many others.

From July 1972 to January 1973, he was the drummer for The Byrds and joined the L.A. Express later that year. The band served as Joni Mitchell’s back-up band on tour during the mid- to late-1970s; Guerin had a brief relationship with Mitchell during that time. She later wrote the song Hejira about leaving him.
