John Frank Rieley III (November 24, 1942 – April 17, 2015) was an American businessman, record producer, songwriter, and disc jockey who managed the Beach Boys between mid-1970 and late 1973.

"[2] Rieley co-wrote a total of ten songs included on the Beach Boys' albums Surf’s Up (1971), Carl and the Passions – "So Tough" (1972), and Holland (1973).

He also sang lead on the Surf's Up track "A Day in the Life of a Tree" and narrated Brian Wilson's fairy tale Mount Vernon and Fairway (1972).

Following his work with The Beach Boys, Rieley made the rock book project Western Justice with Machiel Botman in 1975.

In 1995, Rieley, along with Muller, founded e-fax pioneer J2 Global, Inc., which later became Ziff Davis following its $167 million acquisition of the digital publishing company.
