The IFL National Championship (previously known as the United Bowl) is the annual indoor American football game that determines the champion of the Indoor Football League (IFL). The game culminates a season of the same year and is the conclusion of the IFL playoffs. The winner receives the IFL National Championship Trophy. The contest is held in an American city, chosen by the IFL in three-year agreements. Since August 2022, the winner of the Eastern Conference Championship Game has faced the winner of the Western Conference Championship Game in the culmination of the IFL playoffs.
