James Newell Osterberg, Jr. (born April 21, 1947), better known by his stage name Iggy Pop, is an American rock singer, songwriter, and occasional actor. Although he has had only limited commercial success, Iggy Pop is considered one of the most important innovators of punk and related styles. He is sometimes referred to by the nicknames "the Godfather of Punk" and "the Rock Iguana", and is widely acknowledged as one of the most dynamic stage performers of rock. Pop began calling himself Iggy after his first band in high school, The Iguanas. His direct influence extends to the present day: a Cadillac ad in rotation since February 2007 features his vocal performance on the song "Punkrocker", recorded in 2006 with the Swedish band Teddybears.

Iggy Pop was the lead singer of The Stooges, a late 1960s/early 1970s garage rock band who were influential in the development of the nascent heavy metal and punk rock genres. The Stooges became infamous for their live performances, during which Iggy Pop would take drugs, self-harm, and leap off the stage (being among the first to "stage dive"). Many subsequent performers have imitated Pop's antics.

Pop has had varying degrees of success in the course of his subsequent solo career. His best-known solo songs include "Lust for Life", "I'm Bored", "Real Wild Child", the Top 40 hit "Candy" (with vocalist Kate Pierson of The B-52's) and "The Passenger". A film about Iggy Pop's life and career titled The Passenger is currently in development.
