Silat is the collective term for a class of indigenous martial arts from the Nusantara and surrounding geocultural areas of Southeast Asia. It is traditionally practised in Brunei, Indonesia, Malaysia, Singapore, Southern Thailand, Southern Philippines and Southern Vietnam. There are hundreds of different styles (aliran) and schools (perguruan) which tend to focus either on strikes, joint manipulation, weaponry, or some combination thereof.

Martial arts are codified systems and traditions of combat practiced for a number of reasons such as self-defence; military and law enforcement applications; competition; physical, mental, and spiritual development; entertainment; and the preservation of a nation's intangible cultural heritage.
