Rutherglen Glencairn F.C. were formed in 1895 at the 'Old Jail' office in Rutherglen.

The Glens played their first-ever game on 15 August 1896 against the Ibrox XI (Rangers' junior string in those days) and the Glens won 1–0.
The Southcroft team joined the Glasgow Junior League and won it in 1899–1900 to take possession of the "Evening Times Trophy".

The Glens' big moment did not arrive until season 1901–02 when they won the Scottish Junior Cup, the Glasgow League Championship, and the Glasgow Exhibition Championship.
The team that proudly brought the Scottish Junior Cup to Rutherglen for the first time by beating Maryhill 1–0 at Meadowside is considered as one of the greatest ever, including future Scotland senior international forwards Jimmy McMenemy and Alec Bennett, both natives of the town.

It was not until 1918–19 that the Glens won the Scottish Junior Cup again, beating St Anthony's 1–0.

Glencairn's third Scottish Junior Cup win was in season 1926–27 and the satisfaction was all the greater because it was Cambuslang Rangers, their great local rivals, who were defeated 2–1.
The Glens won the Scottish Junior Cup again for the last time in season 1938-39 when Shawfield (the other local rivals, from Oatlands) went down 2–1.

Glencairn's recent success has been in their rise through the junior leagues in which they were crowned champions of both the West of Scotland League Central District First Division in 2009 and the West of Scotland Super League First Division in 2010.

In 2020, the club confirmed their intention to leave the separate Junior setup and join a proposed feeder division for the Lowland Football League, part of the pyramid system below the professional level of the Scottish game.
