The club's most distinct rivalry is with Glasgow neighbours Celtic F.C.; the two clubs are collectively known as the Old Firm.
Rangers' traditional support is largely drawn from the Protestant Unionist community, whilst Celtic's traditional support is largely drawn from the Catholic community.
The first Old Firm match was won by Celtic and there have been over four hundred matches played to date.
The Old Firm rivalry has fuelled many assaults, sometimes leading to deaths, on Old Firm derby days; an activist group that monitors sectarian activity in Glasgow has reported that on Old Firm weekends, admissions to hospital emergency rooms have increased over normal levels and journalist Franklin Foer noted that in the period from 1996 to 2003, eight deaths in Glasgow were directly linked to Old Firm matches, as well as hundreds of assaults.

The bitter rivalry with Aberdeen developed following an incident in the 1979 League Cup final when Rangers' Derek Johnstone provoked the fury of the Dons support with what they believed was a blatant dive but which resulted in the dismissal of Aberdeen's Doug Rougvie and a Rangers victory.
Then, the following season, Aberdeen's John McMaster had to be given the kiss of life at Ibrox after a vicious stamp on his throat.
Relations between fans were further soured during a league match on 8 October 1988, when Aberdeen player Neil Simpson's tackle on Rangers' Ian Durrant resulted in Durrant being injured for two years.
Resentment continued and in 1998 an article in Rangers match programme branded Aberdeen fans "scum", although Rangers later issued a "full and unreserved apology" to Aberdeen and their supporters, which was accepted by Aberdeen.

Rangers' relaunch in the Third Division in the 2012–13 season led to the club's original rivalry with Queen's Park being renewed for the first time since 1958 in the league.
Rangers and Queen's Park first played each other in March 1879, some nine years before the start of the Old Firm rivalry.
Matches with Queen's Park were advertised as the "Original Glasgow Derby" by Rangers and the Scottish media; and as the "Oldest Derby in the World" by Queen's Park.
