The Campeonato Argentino Abierto de Polo is an international polo championship at club level, organised every year since 1893 at the Campo Argentino de Polo of Palermo, Buenos Aires.

Polo is a ball game that is played on horseback, a traditional field sport and one of the world's oldest known team sports. The game is played by two opposing teams with the objective of scoring using a long-handled wooden mallet to hit a small hard ball through the opposing team's goal. Each team has four mounted riders, and the game usually lasts one to two hours, divided into periods called chukkas or chukkers.
