The Battle of Santiago (Italian: Battaglia di Santiago, Spanish: Batalla de Santiago) was a football match during the 1962 FIFA World Cup, played between host Chile and Italy on 2 June 1962 in Santiago. It gained its nickname from the level of violence seen in the game, in which two players were sent off, numerous punches were thrown and police intervention was required four times. The referee was Ken Aston, who later went on to invent yellow and red cards.

The 1962 FIFA World Cup was the seventh edition of the FIFA World Cup, the quadrennial international football championship for senior men's national teams. It was held from 30 May to 17 June 1962 in Chile. The qualification rounds took place between August 1960 and December 1961, with 56 teams entering from six confederations, and fourteen qualifying for the finals tournament alongside Chile, the hosts, and Brazil, the defending champions.

Brazil successfully defended their World Cup title, defeating Czechoslovakia 3–1 in the final in the Chilean capital of Santiago. They became the second team, after Italy in 1934 and 1938, to win the World Cup twice consecutively; no team has since achieved the feat. Host nation Chile finished third, defeating Yugoslavia 1–0 in the third-place play-off.

The tournament was marred by violence between players on the pitch and a toxic atmosphere; it included the first-round match between Chile and Italy (2–0), which became known as the Battle of Santiago, one of a number of violent matches played throughout the tournament. It was the first World Cup that used goal average as a means of separating teams with the same number of points. It was also the first World Cup in which the average number of goals per match was less than three (2.78); this has been repeated at every World Cup since, despite expansion of the tournament.
