Paul Mars Black is an American singer and drummer. He is most notable for his time as lead vocalist in L.A. Guns, with whom he wrote most of their self-titled debut album.

L.A. Guns are an American glam metal band from Los Angeles, formed in 1983. The lineup currently consists of Tracii Guns, Phil Lewis, Ace Von Johnson, Johnny Martin, Adam Hamilton and Shawn Duncan. The first incarnation of the group was formed by Tracii Guns and Rob Gardner in 1983 and merged with fellow Los Angeles group Hollywood Rose to form Guns N' Roses in March 1985. After only a brief tenure in that band, Guns reformed L.A. Guns with a new lineup, consisting of Paul Black, Mick Cripps, Robert Stoddard, and Nickey Alexander. Black would soon be replaced by former Girl singer Phil Lewis while former Faster Pussycat bassist Kelly Nickels was added to the group. Later, Alexander would be replaced by former W.A.S.P. drummer Steve Riley with this being known as the "classic lineup" of L.A. Guns. They achieved moderate chart success in the late 1980s and early 1990s. However, the group went through numerous lineup changes and failed to regain mainstream attention.
