Wrestling is a form of combat sport involving grappling type techniques such as clinch fighting, throws and takedowns, joint locks, pins and other grappling holds. A wrestling bout is a physical competition, between two (occasionally more) competitors or sparring partners, who attempt to gain and maintain a superior position. There are a wide range of styles with varying rules with both traditional historic and modern styles. Wrestling techniques have been incorporated into other martial arts as well as military hand-to-hand combat systems.

The term wrestling is attested in late Old English, as wræstlunge (glossing palestram).

Wrestling is one of the oldest forms of combat with references to it as early as the Iliad, in which Homer recounts the Trojan War in the 13th or 12th century BC. The origins of wrestling can be traced back 15,000 years through cave drawings in France. Babylonian and Egyptian relief's show wrestlers using most of the holds known to the present-day sport. In ancient Greece, wrestling occupied a prominent place in legend and literature; wrestling competition, brutal in many aspects, was the number one sport of the Olympic Games. The ancient Romans borrowed heavily from Greek wrestling, but eliminated much of its brutality.
