The Frontier League (FL; French: Ligue Frontière, LF) is a professional baseball league in North America composed of 18 teams – 15 in the United States and 3 in Canada. The FL is one of the four independent baseball leagues that is considered to be an MLB Partner League, and the level of play is comparable to the High-A level. The league is headquartered in Sauget, Illinois.
The Frontier League was organized by several men who got together in the winter of 1992-1993 and decided to start an independent professional baseball league to serve the West Virginia, eastern Kentucky and southeast Ohio areas. They believed they could bring professional baseball to areas that would never have a chance of affiliated professional baseball coming to their communities. The seed was planted and they named their project The Frontier League.
25 distinct franchises had competed in the league. Its largest period of growth followed in 2020–21, when six teams from the ceased Can-Am and New York–Penn leagues joined alongside an expansion franchise. The Evansville Otters, the only one of the original eight franchises still playing today, is the longest tenured team in the league.
The FL is one of the seven independent baseball leagues in North America, and one of the four that is considered to be an official partner of Major League Baseball; the others are the Atlantic League, the American Association as well as the Pioneer League.
The league's regular season is typically held from May to September, with each team playing 96 games. Following the conclusion of the regular season, 8 teams advance to the Frontier League playoffs, a three-round tournament that runs into mid-September to determine the league champion. Since the league's founding in 1993, the Schaumburg Boomers have won the most combined league titles with 4, winning two in a row in 2013 and 2014. The reigning league champions are the Québec Capitales, who defeated the Washington Wild Things in the 2024 Frontier League Championship Series.
