The Frontier League (FL; French: Ligue Frontière, LF) is a professional baseball league in North America consisting 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.
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, while the Schaumburg Boomers have won the most championships.
The FL'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 playoffs, a three tournament that runs approximately two weeks to determine the league champion.
