Filipino martial arts (FMA) refer to ancient and newer modified fighting methods devised in the Philippines. It incorporates elements from both Western and Eastern Martial Arts; the most popular forms of which are known as Arnis, Eskrima, and Kali. The intrinsic need for self-preservation was the genesis of these systems. Throughout the ages, invaders and evolving local conflict imposed new dynamics for combat in the islands now making up the Philippines. The Filipino people developed battle skills as a direct result of an appreciation of their ever-changing circumstances. They learned, often, out of necessity on how to prioritize, allocate and use common resources in combative situations. Filipinos have been heavily influenced by a phenomenon of cultural and linguistic mixture. Some of the specific mechanisms responsible for cultural and martial change extended from phenomena such as war, political and social systems, technology, and trade and practicality.

Arnis, also known as kali or eskrima/escrima, is the national martial art of the Philippines. These three terms are, sometimes, interchangeable in referring to traditional martial arts of the Philippines, which emphasize weapon-based fighting with sticks, knives, bladed weapons, and various improvised weapons, as well as "open hand" techniques without weapons.
