Argentina Open

The Argentina Open or Abierto Argentino is an annual ATP men's tennis event held in Buenos Aires, Argentina. The tournament is listed as an ATP 250 on the ATP Tour, and is played on outdoor clay courts at the 5,500 capacity Buenos Aires Lawn Tennis Club, in the Palermo barrio (neighborhood). Usually held in February, it includes both singles and doubles events.
The tournament was established in 1927 as the Argentina International Championships and was a combined men's and women's event from 1928 until 1987 when the women's tournament was discontinued (after 34 years the women's event resumed in 2021). Between 1970 and 1988 it was part of the Grand Prix tennis circuit and a Grand Prix Super Series event (1970–71). Between 1993 and 1995 it was part of the ATP World Series.
This event is not to be confused with the Argentine Championships (1918-1997), which was the open national championships of Argentina held at the Tennis Club Argentino (founded 1913) also in Buenos Aires.
The tournament is presented by the City of Buenos Aires. Previously the event was known by different names such as Argentina International Championships (1927–1967), South American Open (1968–1974), ATP Buenos Aires (1978–80, 1993–95), Copa AT&T and Copa Telmex. The original tournament was founded as a combined men's and women's championship from 1928 until 1987.
For the years 1946-1951, 1955, 1957-1967 this tournament also carried the joint denomination of South American Championships. For the years 1968-1971, 1973-1981 it carried the joint denomination of South American Open Championships or South American Open. Since 2001, it has been listed in the ATP Tour 250 category (called ATP International Series category until 2009).
Renowned players, including former world No. 1s such as Spaniards Rafael Nadal, a 14-time Roland Garros champion, Carlos Alcaraz, and Carlos Moyá, as well as Brazilian Gustavo Kuerten have lifted the trophy. Other champions include Dominic Thiem, Casper Ruud, and David Ferrer, a former world No. 3 and three-time winner of the IEB+ Argentina Open.
It is also worth highlighting the local players who managed to capture the title. In the 2000s, the so-called “Argentine Legion” left its mark with victories from Gastón Gaudio (2005), Guillermo Coria (2004), and David Nalbandian (2008). Later, Juan Mónaco secured the title in both 2007 and 2012, establishing himself as one of the tournament’s most successful players in the modern era. Other Argentine champions include Diego Schwartzman, who won in 2021, and Facundo Díaz Acosta in 2024. These achievements reflect Argentina’s strong tennis tradition in the tournament, making it a key stage for the development of national players within the ATP circuit.
In 2025, the event became the first clay-court tournament to incorporate the Live Electronic Line Calling (ELC) system, an automated version of Hawk-Eye that replaces line judges. This technology was introduced to enhance the accuracy of officiating decisions and minimize human errors. The implementation of this system marked a significant shift in clay-court tennis, ushering in a new era where technology plays a crucial role in ensuring fair and efficient officiating.
This court hosts the main matches of both the qualification and final rounds. It has a seating capacity of 4,950 spectators, which can be extended to 5,750 in certain editions thanks to an auxiliary stand with space for 800 additional spectators.
This venue hosts medium-attendance matches, with the primary goal of optimizing the schedule by allowing multiple games to take place simultaneously and preventing tournament delays. This enhances the event’s flow and provides more opportunities for players. It features two tubular stands positioned along the sidelines, accommodating up to 600 spectators.
