# List of IFL seasons

The Indoor Football League (IFL) is an indoor American football league in the United States and the oldest active professional indoor football league in North America. It was formed in 2008 when the Intense Football League and United Indoor Football merged after the champions of both leagues faced off in the 2008 National Indoor Bowl Championship.
Originally the teams were split into the Intense Conference and the United Conference with the champions facing in the United Bowl. In 2018, the league lost four of its ten teams, leading to the dissolution of the conferences. The top four teams made the IFL playoffs in 2018, the top six made it in 2019, and the top eight made it in 2021. Before the 2022 season, the United Bowl was rebranded to the IFL National Championship and the Eastern Conference and the Western Conference were founded. Since then the conference champions have met in the IFL National Championship.
