BASSINTHEGRASS is the largest music festival in the Northern Territory of Australia and has been held annually since 2003 in the territory capital. The festival is operated by the Northern Territory Government through the Northern Territory Major Events Company, part of a project of the previous Martin government to bring prominent bands to the territory and showcase local talent. BASSINTHEGRASS has grown rapidly since its inception, resulting in the imposition of cap on ticket numbers in 2007.

The festival was first held in 2003 to fulfill a campaign promise by the government to hold a Big Day Out-style youth concert in the territory. It was held in both Darwin and Alice Springs in its inaugural year, with the Alice Springs leg later becoming the Bassinthedust festival. 5000 people attended the Darwin leg, with a further 1500 in Alice Springs, listening to headline acts The Living End, 30 Odd Foot of Grunts and NoKTuRNL. It became an annual event.
