Ninja High School were a Canadian dance-punk band, based in Toronto, Ontario, who merged hip hop and hardcore punk influences.

The group has its origins at parties in Guelph, Ontario, where frontman Matt Collins rapped while looping samples of James Brown.

In 2005, the band signed a distribution deal with German record label Tomlab,[2] which also released the two-song "It's All Right to Fight" as part of its Alphabet Series.

The Globe and Mail has referred to the band as "popular theoretical-rap cheer squad Ninja High School".

[4] Chart magazine wrote that the album Young Adults Against Suicide "is thoughtful, catchy and, for a lo-fi recording, it sounds awesome" and went on to call "Invasion Party" "hands-down one of the best tracks of the year."
