Tifo (Italian: [ˈtiːfo]) is the phenomenon whereby tifosi of a sports team make a visual display of any choreographed flag, sign or banner in the stands of a stadium, mostly as part of an association football match. Tifo is most commonly seen in important matches, local derbies, and rivalries, and although the tradition originated at club teams, some national teams also have fans that organise tifo on a regular basis. Tifo is primarily arranged by ultras or a supporter club to show their love to the club, but are sometimes sponsored or arranged by the club itself.
