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.
