Stone Temple Pilots (also known as STP) is an American rock band formed in San Diego, California, in 1989. Originally consisting of Scott Weiland (lead vocals), brothers Dean (guitar) and Robert DeLeo (bass, backing vocals), and Eric Kretz (drums), the band's lineup remained unchanged from its formation until the firing of Weiland in February 2013. Vocalist Chester Bennington joined the band in May 2013 but left amicably in November 2015. In 2016, STP launched an online audition for a new lead vocalist; Jeff Gutt was announced as STP's new lead singer on November 14, 2017.

After forming under the name Mighty Joe Young, the band signed with Atlantic Records and changed its name to Stone Temple Pilots. Their debut album, Core, released in 1992, was a major commercial hit, and STP went on to become one of the most successful bands of the 1990s, selling more than 18 million albums in the United States and 40 million worldwide. STP released four more studio albums: Purple (1994), Tiny Music... Songs from the Vatican Gift Shop (1996), No. 4 (1999), and Shangri-La Dee Da (2001), before separating in 2003, after which the band members partook in various projects (most notably Velvet Revolver and Army of Anyone). STP eventually reconvened in 2008 for a reunion tour, released their self-titled sixth album with Scott Weiland in 2010. After firing Weiland in 2013, the band recruited Chester Bennington, who they would tour with as their lead vocalist up until Bennington's departure in 2015. The band's only material with Bennington was the EP High Rise, in 2013. STP has released two albums with Gutt on vocals: its second self-titled album in 2018 and eighth studio album, Perdida, in 2020.

While initially rising to fame as part of the grunge movement of the early 1990s, further releases from the band expressed a variety of influences, including psychedelic rock, bossa nova, and classic rock. STP's evolution throughout the 1990s and early 2000s involved periods of commercial highs and lows, brought about in part by Weiland's well-publicized struggles with drug addiction.
