Rangers Football Club is a professional football club in Glasgow, Scotland. The team competes in the Scottish Premiership, the top division of Scottish football. The club is often referred to colloquially as Glasgow Rangers, particularly outside Scotland, though this has never been its official name. The fourth-oldest football club in Scotland, Rangers was founded by four teenage boys as they walked through West End Park in March 1872 where they discussed the idea of forming a football club, and played its first match against the now defunct Callander at the Fleshers' Haugh area of Glasgow Green in May of the same year. Rangers' home ground, Ibrox Stadium, designed by stadium architect Archibald Leitch and opened in 1929, is a Category B listed building and the third-largest football stadium in Scotland. The club has always played in royal blue shirts.

The Scottish Premiership known as the cinch Premiership for sponsorship reasons, is the top division of the Scottish Professional Football League (SPFL), the league competition for men's professional football clubs in Scotland. The Scottish Premiership was established in July 2013, after the SPFL was formed by a merger of the Scottish Premier League and Scottish Football League. There are 12 teams in this division, with each team playing 38 matches per season. Sixteen clubs have played in the Scottish Premiership since its creation in the 2013–14 season. Celtic are the current league champions, having won the 2022–23 Scottish Premiership.
