Jane's Addiction is an American rock band from Los Angeles, formed in 1985. The band consists of vocalist Perry Farrell, guitarist Dave Navarro, drummer Stephen Perkins and bassist Eric Avery. Jane's Addiction was one of the first bands from the early 1990s alternative rock movement to gain both mainstream media attention and commercial success in the United States.

Founded by Farrell and Avery, following the disintegration of Farrell's previous band Psi Com, Jane's Addiction's first release was a self-titled live album, Jane's Addiction (1987), which caught the attention of Warner Bros. Records. The band's first two studio albums, Nothing's Shocking (1988) and Ritual de lo Habitual (1990), were released to widespread critical acclaim, and an increasing cult fanbase. As a result, Jane's Addiction became icons of what Farrell dubbed the "Alternative Nation". The band's initial farewell tour, in 1991, launched the first Lollapalooza, which has since become a perennial alternative rock festival.

In 1997, the band reunited with Flea of the Red Hot Chili Peppers replacing Avery on bass guitar for a one-off tour. In 2001, a second reunion took place, with Martyn LeNoble—and later Chris Chaney—occupying the role of bass guitarist. In 2003, the band released its third studio album, Strays, before dissolving again the following year. In 2008, the band's original line-up reunited and embarked on a world tour. Avery acrimoniously left the band in early 2010, as the group began working on new material. In 2011, the band released its fourth studio album, The Great Escape Artist, with Chaney returning to the band for its recording and subsequent tour.

Between the years of 2012 and 2022, the band remained active with occasional tours and performances. In August 2022, Avery rejoined the band after a twelve-year absence. Due to ongoing struggles with long COVID, Navarro was replaced by Queens of the Stone Age guitarist Troy Van Leeuwen and former Red Hot Chili Peppers guitarist Josh Klinghoffer on tours across 2022 and 2023. In 2024, Navarro returned to Jane's Addiction, marking the full reunion of the band's classic-era line-up.
