Football

Chile competed in men's football for the first time in 1928. The team lost its first match against Portugal, 4–2, and were eliminated from the single-elimination tournament. Chile also played in a consolation tournament, defeating Mexico before playing the Netherlands to a full-time draw. After a coin toss the Netherlands were declared winners and were handed the trophy which had been on offer (by the NVB), but gave it to Chile to take home as a 'memento' of the Netherlands, the Olympic Games and their Dutch football friends.

Swimming

4 swimmers, all men, represented Chile in 1928. It was the nation's debut appearance in the sport.
