Justin Gunnar Walter Chancellor (born 19 November 1971) is an English musician, best known as the bassist for rock band Tool, a position he has held since 1995. Prior to joining Tool, he played in a band called Peach. After settling in the US, along with his engagement in his musical projects, he and his wife Shelee Dykman Chancellor ran a store called Lobal Orning in Topanga, California, dedicated to music and literature "that shaped and changed" both of them. The store closed in 2008. He started M.T.Void music project with Piotr "Glaca" Mohammed from Sweet Noise.

Early life
Chancellor is of English and Norwegian descent. He was educated at Tonbridge School in Kent, England, where he was the bass player for a school band named Slice of Life and used to perform a cover version of Corey Hart's "Sunglasses at Night" in the dining room of his boarding house. The band released an eponymous titled tape featuring a song of the same name. Chancellor went on to study at Durham University.

Career
Chancellor later joined the band Peach. Peach released the album Giving Birth to a Stone and two EPs, and supported Tool in 1994 in Europe before breaking up in 1995. In September that year, Chancellor moved to the United States and joined Tool full-time to replace Paul D'Amour who departed during the recording of the band's second full-length album. Chancellor has been a full member of the band since the 1996 studio album Ænima.
