Aruba sent a delegation to compete at the 2004 Summer Olympics in Athens, Greece from 13 to 29 August 2004. The delegation's participation in the Athens Olympics marked Aruba's fifth appearance at the Summer Olympics since the Dutch colony's debut at the 1988 Summer Olympics in Seoul, South Korea. Four athletes (three men and one woman) competed across three sports (Pierre de Windt in track and field, Davy Bisslik and Roshendra Vrolijk in swimming, and Isnardo Faro weightlifting). None of the track or swimming athletes advanced past the first round in their events, and as of Athens, no Arubans had medaled in any events. Roshendra Vrolijk bore Aruba's flag at the ceremonies.

Aruba is a small island colony of 100,000 people that is part of the Kingdom of the Netherlands, and has been under Dutch control since the 1630s. The island lies in the southern Caribbean Sea just to north of Venezuela, and is near to the Dutch colonies of Curaçao and Bonaire. The colony originally was part of an autonomous union with those two islands in what was known as the Netherlands Antilles, but Aruba seceded from that union in 1986. The Netherlands continues to regulate all its foreign affairs. While the first Dutch Antilean delegation to the Olympics was sent during the 1952 Summer Olympics in Helsinki, Finland, the first uniquely Aruban delegation participated two years after the island's secession from the Netherlands Antilles at the 1988 Summer Olympics in Seoul, South Korea. Between then and the 2004 Athens Olympics, Aruba had sent a delegation to all five Summer Olympic games. The most substantial Aruban delegation was in 1988, when it included eight athletes. This delegation included more women and encompassed more sports than any Aruban delegation since then (including the Athens Olympics).

At the Athens Olympics, four athletes (three men and one woman) participated across three sports in four distinct events. Swimmer Roshendra Vrolijk was Aruba's flag bearer at the ceremonies.

Aruban athletes have so far achieved qualifying standards in the following athletics events (up to a maximum of 3 athletes in each event at the 'A' Standard, and 1 at the 'B' Standard).

Pierre "Peppie" de Windt participated on Aruba's behalf as its only athlete in a track and field event. Born in the Solito neighborhood of Aruba's capital city, Oranjestad, de Windt was 21 at the time he ran at the Olympics in Athens. The Aruban athlete had not previously participated in any Olympic games. The event's first round took place during the 21st of August. de Windt took part in the fourth heat against eight other athletes, although Greece's Hristoforos Hoidis did not start. In his heat, de Windt placed sixth with a time of 11.02 seconds. Paraguay's Diego Ferreira ranked fifth ahead of de Windt, setting a national record in the process (10.50 seconds), while Laotian athlete Chamleunesouk Ao Oudomphonh ranked directly behind de Windt (11.30 seconds). The leaders of de Windt's heat included first place finalist Shawn Crawford of the United States (10.02 seconds) and Barbados' Obadele Thompson, who placed second and set his season best (10.08 seconds). The Aruban sprinter did not advance to later rounds.

Isnardo "Junior" Faro participated in the 2004 Athens Olympics as Aruba's only weightlifter. Born in Aruba in July 1978, Faro was 18 at the time he represented Aruba at the 1996 Atlanta Olympics, where he finished in 21st place of the men's middleweight class.
