Jeffrey Foskett (February 17, 1956 – December 11, 2023) was an American guitarist and singer, best known as a touring and studio musician for Brian Wilson and the Beach Boys since the 1980s.

Born and raised in San Jose, California,[3] Foskett began his first band in the 1970s known as Cherry, after the Willow Glen area street on which he lived.

The band held a house residency at The Troubadore Nightclub in Hollywood Mondays performing with The Mentors, The Cretones, The Police and 20/20.

In 1976, Foskett tracked down Wilson's house in Bel Air, which had a stained-glass window resembling the artwork of the 1967 album Wild Honey.

In late 1979, Wilson's cousin Mike Love stopped by the famous Santa Barbara restaurant "1129" where Reverie was the house band.

Love listened to Foskett and hired Reverie as the original incarnation of The Endless Summer Beach Band.

When Carl rejoined the Beach Boys in May 1982, Foskett was asked to stay to perform Wilson's falsetto parts, which he did until 1990.

In addition to The Beach Boys/Brian Wilson, Foskett toured and recorded with other friends in the music industry such as Paul McCartney, Jeff Beck, Roy Orbison, The Everly Brothers, Christopher Cross, Michael McDonald, Chicago, America, Heart, Roger McGuinn, Eric Carmen, Eric Clapton, Jimmy Page, and Ringo Starr.
