Ronald Montague Moss (born March 4, 1952) is an American actor, musician and singer/songwriter, a member of the band Player, and best known for portraying Ridge Forrester, the dynamic fashion magnate on the CBS soap opera The Bold and the Beautiful from 1987 to 2012.

In 1976, Moss joined creative forces with fellow singer/guitarist Peter Beckett, singer/guitarist/keyboardist J.C Crowley, and drummer John Friesen to form the band Player, primarily as bassist and singer.

The Australian edition of his 2002 solo CD I'm Your Man includes a fresh duet of the original hit "Baby Come Back" and two bonus tracks: "That's When I'll Be Gone" and "Mountain".

1987 also marks the year of Moss' most critically acclaimed cinematic role as Rowdy Abilene in the Andy Sidaris classic Hard Ticket to Hawaii.

The punchline of the advertisement was "you can tell when it's not all Aussie"— a line intended to show (in jest) that, while Moss has longstanding connections with Australia, his Hollywood career has resulted in his persona differing significantly from that of the cliché Australian male.

The Bold and the Beautiful was a very popular prime-time show in much of Europe; in 2010, Moss was a participant in the Italian version of Dancing with the Stars, finishing second with his partner Sara Di Vaira.

On May 12, 2014, Moss, along with his band, appeared on the ABC daytime soap opera General Hospital as part of the 2014 Nurses' Ball, where they performed their hit single "Baby Come Back".
