Philip Anthony Campbell is a Welsh rock musician, best known as the guitarist in Motörhead from 1984 to 2015. The band disbanded upon the death of founder and frontman Lemmy. He currently tours with his own band Phil Campbell and the Bastard Sons, featuring his three sons: Todd, Dane and Tyla.

Motörhead were an English rock band formed in London in 1975 by bassist and lead vocalist Lemmy Kilmister, guitarist Larry Wallis and drummer Lucas Fox. Lemmy was also the primary songwriter and only constant member. The band are often considered a precursor to the new wave of British heavy metal, which re-energised heavy metal in the late 1970s and early 1980s. Though several guitarists and drummers have played in Motörhead, most of their best-selling albums and singles feature drummer Phil "Philthy Animal" Taylor and guitarist "Fast" Eddie Clarke.
