United Indoor Football (UIF) was an indoor American football league in the United States that operated from 2005 to 2008. Ten owners from the National Indoor Football League, including one expansion (the Dayton Warbirds, which never played a game in UIF) and two from arenafootball2 (af2) took their franchises and formed their own league. The league was based in Omaha, Nebraska.
On July 22, 2008, it was announced that the UIF would be merging with the Intense Football League for the 2009 season. The merged league is known as the newest incarnation of the Indoor Football League.
