James Newell Osterberg Jr. (born April 21, 1947), known professionally as Iggy Pop, is an American singer, musician, songwriter, actor and radio broadcaster. He was the vocalist and lyricist of proto-punk band the Stooges, who were formed in 1967 and have disbanded and reunited many times since. Often called the "Godfather of Punk", he was named one of the 50 Great Voices by NPR. In 2010, he was inducted into the Rock and Roll Hall of Fame as a member of the Stooges. Pop also received a Grammy Lifetime Achievement Award in 2020 for his solo work.

Initially playing a raw, primitive style of rock and roll (progressing later towards more experimental and aggressive rock), the Stooges sold few records in their original incarnation and gained a reputation for their confrontational performances, which often involved acts of self-mutilation by Pop. He had a long collaborative relationship and friendship with David Bowie over the course of his career, beginning with the Stooges' album Raw Power in 1973. Both musicians went to West Berlin to wean themselves off their respective drug addictions and Pop began his solo career by collaborating with Bowie on the 1977 albums The Idiot and Lust for Life, Pop usually contributing the lyrics. Throughout his career, he is well known for his outrageous and unpredictable stage antics, poetic lyrics and distinctive voice. He was one of the first performers to do a stage-dive and popularized the activity. Pop, who traditionally (but not exclusively) performs bare-chested, also performed such stage theatrics as rolling around in broken glass and exposing himself to the crowd.

Pop's music has encompassed a number of styles over the course of his career, including garage rock, punk rock, hard rock, heavy metal, art rock, new wave, grunge, jazz, blues and electronic. Though his popularity has fluctuated, many of Pop's songs have become well known, including "Search and Destroy" and "I Wanna Be Your Dog" by the Stooges, and his solo hits "Lust for Life", "The Passenger" and "Real Wild Child (Wild One)". In 1990, he recorded his only Top 40 U.S. hit, "Candy", a duet with B-52's singer Kate Pierson. Pop's song "China Girl" became more widely known when it was re-recorded by co-writer Bowie, who released it as the second single from his most commercially successful album, Let's Dance (1983). Bowie re-recorded and performed many of Pop's songs throughout his career.

Although Pop has had limited commercial success, he has remained a culture icon and a significant influence on a wide range of musicians in numerous genres. The Stooges' album Raw Power has proved an influence on artists such as Sex Pistols, the Smiths, and Nirvana. His solo album The Idiot has been cited as a major influence on a number of post-punk, electronic and industrial artists including Depeche Mode, Nine Inch Nails and Joy Division, and was described by Siouxsie Sioux as a "re-affirmation that our suspicions were true: the man is a genius."
