Glentoran Football Club is a semi-professional football club that plays in the NIFL Premiership. The club was founded in 1882 and plays its home games at the Oval in east Belfast. Club colours are red, green and black. Linfield and Glentoran are nicknamed Belfast's Big Two, as they have traditionally dominated local football in Northern Ireland since the demise of Belfast Celtic. The two play a league match on Boxing Day each year, which regularly attracts the largest attendance of the Irish League season.
