Crusaders Football Club is a three quarter professional Northern Irish football club playing in the NIFL Premiership. The club, founded in 1898, hails from Belfast and plays its home matches at Seaview.
Crusaders originally played as a junior team, and then played intermediate football until 1949, and during that time they were one of the top non-league teams in the country, winning the Intermediate League nine times and the Steel & Sons Cup on seven occasions. After the withdrawal of Belfast Celtic, Crusaders were elected in their place in time for the start of the 1949–50 season. Since then the club has won 26 senior trophies including seven league titles, three Irish Cups, two League Cups, seven County Antrim Shields, one Setanta Sports Cup, two Gold Cups, three Ulster Cups and one Carlsberg Cup.
The club's kit colours are red and black, and the current manager is former player Stephen Baxter, who is the club's longest serving manager, having been appointed in 2005. The club's closest rivals are Cliftonville, with whom they contest the North Belfast derby. Rivalries also exist with other Belfast sides such as Linfield and Glentoran.
