Charles Samuel "Chuck" Loeb (December 7, 1955 – July 31, 2017) was an American jazz guitarist and a member of the groups Steps Ahead and Fourplay.

Loeb was born in Nyack, New York, near New York City. At a young age, he listened to Jimi Hendrix, Eric Clapton, Cream, Led Zeppelin, The Beatles, The Rolling Stones, and Bob Dylan. According to a 2005 JazzTimes article, the first song he learned on guitar was Dylan's "Like a Rolling Stone", which he would later play at a guest appearance with Dylan. He discovered jazz when he was sixteen through the music of guitarists Wes Montgomery, George Benson, John McLaughlin, and Pat Martino. At that point, Loeb chose to become a musician and "never thought of doing anything else".
