Rangers Football Club is a Scottish professional football club based in the Govan district of Glasgow. It has played in the Scottish Premiership, the first tier of the Scottish Professional Football League, since winning the 2015–16 Scottish Championship. Their home ground, Ibrox Stadium, in the southwest of the city, is the third largest football stadium in the country. Although not part of the official name, the club is occasionally referred to as Glasgow Rangers. Rangers have played in blue shirts since the inception of the club.
Rangers have won more league titles and domestic trebles than any other club in the world, winning the league title 54 times, the Scottish Cup 33 times and the Scottish League Cup 27 times, and achieving the treble of all three in the same season seven times. Rangers won the European Cup Winners' Cup in 1972 after being losing finalists twice, in 1961 and 1967. A third runners-up finish in Europe came in the UEFA Cup in 2008. Rangers have a long-standing rivalry with Celtic, the two Glasgow clubs being collectively known as the Old Firm, which is considered one of the world's biggest football derbies.
