The 2018 Americas Rugby Championship was the third series of the Americas Rugby Championship (sometimes informally called the "Americas' Six Nations", a reference to Europe's Six Nations Championship), which is the top elite tournament for the Americas nations. It was contested by Argentina XV (Argentina's secondary national team), Canada, United States, Uruguay, Brazil, and Chile. All matches were full international test matches with caps awarded, except those involving Argentina XV.
The Championship was retained by the United States, who became the first nation to win the Grand Slam ARC title, winning all five games.
