Less Than Jake is an American ska punk band from Gainesville, Florida, formed in 1992. The band consists of Chris DeMakes (guitars, vocals), Roger Lima (bass, vocals), Buddy Schaub (trombone), Peter "JR" Wasilewski (saxophone) and Matt Yonker (drums).

The group released its debut album, Pezcore, in 1995, following a series of independent seven-inch single releases. The band's subsequent two studio albums, Losing Streak (1996) and Hello Rockview (1998), were released on a major label, Capitol Records, leading to increased exposure. The band's fourth album, Borders and Boundaries, was released in 2000 on Fat Wreck Chords. The band's fifth studio album, Anthem (2003), was the group's most commercially successful to date, featuring the singles "She's Gonna Break Soon" and "The Science of Selling Yourself Short".

In 2008, the band founded its own label, Sleep It Off Records, and released its seventh full-length album, GNV FLA. The band has recently stated its preference for EP releases, and independently issued Greetings from Less Than Jake (2011) and its counterpart, Seasons Greetings from Less Than Jake (2012). In late 2012, the band combined the two to create the compilation album Greetings and Salutations (2012). The band's eighth studio album, See the Light, was released on November 12, 2013.

In February 2017, the band released Sound the Alarm, an EP which became their final release with founding member, drummer and lyricist Vinnie Fiorello, who departed from the band the following year. Fiorello was replaced by former Teen Idols drummer Matt Yonker, who contributed to the band's ninth studio album, Silver Linings (2020). A seven-song EP, Uncharted, was released in November 2024 and produced by Jason Livermore and Bill Stevenson of Descendents and Black Flag.
