Indonesian martial arts includes a variety of fighting systems native to or developed in the archipelago of Indonesia, both the age-old traditional arts, and the more recently developed hybrid combatives. In the Indonesian language the term bela-diri is used to mean martial art, and in essence the Indonesian fighting arts are meant as one's defence against perceived threat and assault. Other than physical training, they often include spiritual aspects to cultivate inner strength, inner peace and higher psychological ends.

Pencak silat is an umbrella term for a class of related Indonesian martial arts. In neighbouring countries, the term usually refers to professional competitive silat. It is a full-body fighting form incorporating strikes, grappling, and throwing, in addition to weaponry. Every part of the body is used and subject to attack. Pencak silat was practiced not only for physical defense but also for psychological ends. There are hundreds of different pencak silat styles and schools which tend to focus either on strikes, joint manipulation, weaponry, or some combination thereof.
