Los Leones (The Lions) are the only team of the Americas to win a gold medal at the Olympic Games.

They achieved this after defeating Belgium 4–2 in the final at the 2016 Summer Olympics in Rio de Janeiro, Brazil.

At a continental level, Argentina is the most winning team in the Americas, having dominated most tournaments they played, including four gold medals at the Pan American Cup and eleven gold medals at the Pan American Games.

In 2013, during the Hockey World League Semifinals in Johor Bahru, Malaysia, the team along with coach Carlos Retegui decide to name themselves Los Leones (The Lions), matching the nickname chosen by the women's team at the 2000 Summer Olympics in Sydney, Australia.

Argentina didn't have great performances at the Summer Olympics until they won the gold medal at the 2016 edition by defeating Belgium 4–2, when they became the first national hockey team to win that prize for their country.
