Oingo Boingo () was an American new wave band formed by songwriter Danny Elfman in 1979. The band emerged from a surrealist musical theatre troupe, The Mystic Knights of the Oingo Boingo, that Elfman had led and written material for in the years previous. Their highest-charting song, "Weird Science", reached No. 45 on the US Billboard Hot 100.

Oingo Boingo were known for their high-energy live concerts and experimental music, which can be described as combining elements of music such as art, punk, ska, rock, pop, jazz, and world, amongst other genres. The band's body of work spanned 17 years, with various genre and line-up changes. Their best-known songs include "Only a Lad", "Little Girls", "Dead Man's Party" and "Weird Science".

The band had experienced multiple line-up changes, with Leon Schneiderman, Dale Turner, Sam Phipps, Danny Elfman, Steve Bartek, and John "Vatos" Hernandez being the constant members for most of their history. As a rock band, Oingo Boingo started as a ska and punk-influenced new wave octet, achieving significant popularity in Southern California. During the mid-1980s, the band adopted a more pop-oriented style, until a significant genre change to alternative rock in 1994. At that point, the name was shortened to simply Boingo and the keyboard and horn section were dropped. The band retired after a farewell concert on Halloween 1995, for which they reverted to the name Oingo Boingo and readopted the horn section.
