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.
In 2018, the league lost four of its ten teams, leading to the dissolution of the conferences.
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.
