Peru at the 2004 Summer Olympics

Peru competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004. This was the nation's fifteenth appearance at the Olympics, except the 1952 Summer Olympics in Helsinki.

Comité Olímpico Peruano sent the nation's smallest ever team to the Games since the 1956 Summer Olympics in Melbourne. A total of twelve athletes, seven men and five women, competed in ten different sports. Two athletes from the Peruvian team had previously competed in Sydney: butterfly swimmer Juan Pablo Valdivieso and 1984 Olympic silver medalist Francisco Boza in men's trap shooting (who became the first Peruvian athlete to participate in seven Olympic Games, surpassing a single edition short of a historic record by fellow shooter Juan Giha). Being the oldest and most sophisticated member of the team, Boza was assigned by the committee to become the nation's flag bearer in the opening ceremony. Peru, however, failed to win a single Olympic medal since the 1992 Summer Olympics in Barcelona, where Giha won the silver in the mixed skeet.
