Brazilian Jiu-Jitsu is a martial art and combat sport based on ground fighting (ne-waza) and submission holds. It focuses on the skill of taking an opponent to the ground, controlling one's opponent, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds.

它起源於日本傳統柔術與嘉纳治五郎開創的柔道，由嘉纳治五郎弟子前田光世傳播至巴西。特色是重視地板扭鬥，以槓桿原理控制對手關節，來制服對手。即使身材矮小，也能以這些技巧來打敗對手。
