A free party is a party "free" from the restrictions of the legal club scene, similar to the free festival movement. It typically involves a sound system playing electronic dance music from late at night until the time when the organisers decide to go home. A free party can be composed of just one system or of many and if the party becomes a festival, it becomes a teknival. This typically means that drugs are readily available. The word free in this context is used both to describe the entry fee and the lack of restrictions and law enforcement.

Free festivals are a combination of music, arts and cultural activities, for which often no admission is charged, but involvement is preferred. They are identifiable by being multi-day events connected by a camping community without centralised control. The pioneering free festival movement started in the UK in the 1970s.
