The 2016 Davis Cup was the 105th edition of the Davis Cup, a tournament between national teams in men's tennis. It was sponsored by BNP Paribas. From this season's tournament the deciding set of each match would be settled by a tiebreak at 6 games all rather than playing an advantage set until a player or a team were two games clear. Argentina won their first Davis Cup title, after 4 runner-up finishes, defeating Croatia in the final. Federico Delbonis defeated Ivo Karlović in the final match to give Argentina its first Davis Cup title, after a comeback from Juan Martín del Potro against Marin Čilić in the fourth match.
