Chile at the 1912 Summer Olympics in Stockholm, Sweden was the nation's first official appearance out of four editions of the Summer Olympic Games. Some sources claim that Chile was represented by one athlete, Luis Subercaseaux, at the 1896 Summer Olympics. That cannot be substantiated because the Official Report typically includes only medal winners and Subercaseaux did not win any.

The 1912 Summer Olympics, officially known as the Games of the V Olympiad and commonly known as Stockholm 1912, were an international multi-sport event held in Stockholm, Sweden, between 5 May and 22 July 1912.
