Peter Halsten Thorkelson (February 13, 1942 – February 21, 2019), better known by his stage name Peter Tork, was an American musician and actor. He was best known as the bass guitarist and keyboardist of the Monkees and co-star of the NBC television series of the same name (1966–68).

Tork grew up in Connecticut, and in the mid-1960s as part of the Greenwich Village folk scene in New York City, he befriended musician Stephen Stills. After moving to Los Angeles with Stills, he auditioned for a new musical television sitcom, The Monkees. The series ran from 1966 to 1968 and made Tork and his co-stars teen idols. In addition to albums released with the band, Tork released on Beachwood Recordings one solo album, Stranger Things Have Happened (1994), and later toured with James Lee Stanley, with whom he also recorded three duet albums (Two Man Band, Once Again and Live/Backstage at the Coffee Gallery), as well as his band, Shoe Suede Blues.
