The Argentina women's national field hockey team (Spanish: Selección femenina de hockey sobre césped de Argentina) is governed by the Argentine Hockey Confederation (CAH). The current coach is Fernando Ferrara, who was appointed after Carlos Retegui let go in late 2021. The team is currently second in the FIH Women's World Ranking.
Las Leonas (The Lionesses) have appeared in six Hockey World Cup finals, including the first final in 1974, which they lost 1–0 to the Netherlands. Argentina had to settle with second place in two more finals before winning the tournament for the first time in 2002, beating the Netherlands 4–3 in the final on penalty strokes after a 1–1 draw. Argentina, led by eight-time FIH Player of the Year Luciana Aymar won again in 2010, a 3–1 victory over the Netherlands. Argentina's World Cup-winning coaches are Sergio Vigil in 2002 and Carlos Retegui in 2010.
Argentina has been very successful at the Summer Olympics, winning four consecutive medals (two silver, two bronze) since the 2000 edition, when they became the first women's team in any sport to win an Olympic medal for their country. Luciana Aymar is the only player that has participated and won those four medals. Also, after their first title in 2001 at a Hockey Champions Trophy, they have won the tournament six more times. In front of a home crowd, they won the 2014–15 Hockey World League as the first international title after Aymar's retirement from the national team the previous year.
At a continental level, Argentina has dominated and won every tournament they played, including the Pan American Cup and the Pan American Games leaving the United States with second place on most events until they lost the 2011 Pan American Games final for the first time.
In July 2003, after the implementation of an official World Ranking System, Argentina reached the top of the FIH Women's World Ranking for the first time, reaching it again in 2010 after obtaining the World Cup title and once more in late 2013.
