Amateur wrestling is a variant of wrestling practiced at Olympic, collegiate, scholastic, or other amateur level competitions. There are two international wrestling styles performed at the Olympic Games: freestyle and Greco-Roman. Both styles are under the supervision of the United World Wrestling (UWW).

Wrestling is a martial art and combat sport that involves grappling with an opponent and striving to obtain a position of advantage through different throws or techniques, within a given ruleset. Wrestling involves different grappling-type techniques such as clinch fighting, throws and takedowns, joint locks, pins, and other grappling holds. Many different wrestling techniques have been incorporated into martial arts, combat sports, and military systems. Wrestling is genuine competition; professional wrestling is athletic theatre.
