Dredg (stylized as dredg) is an American rock band formed in 1993 in Los Gatos, California. The band's lineup consists of vocalist Gavin Hayes, guitarist Mark Engles, bassist Drew Roulette and drummer and pianist Dino Campanella.

Originally starting out as an alternative metal outfit, Dredg established themselves in the indie scene with their debut album Leitmotif (1999), which showed the band stylistically moving into progressive rock and art rock; the album's local success landed them a deal with Interscope Records in 2001, who re-released the album later in the year. Dredg's major label debut, El Cielo (2002), was lauded by critics and helped establish a wider cult following for the band. The band experienced mainstream success with Catch Without Arms (2005), which became the band's first album to chart in the United States, and the band received exposure on MTV with the single "Bug Eyes". Following their departure from Interscope in 2009, Dredg independently released The Pariah, the Parrot, the Delusion, which saw the band reach their highest charting positions yet. The band's fifth album, Chuckles and Mr. Squeezy (2011), was a stylistic departure for the band and received a negative response from the band's fanbase. Following the conclusion of the album's promotional tour in May 2014, the band went on an "extended hiatus".

In January 2018, the band announced that they had reunited and have since been writing material for their sixth studio album; they are planning to record the album in the winter of 2022.
