The Lord Provost's Rent Relief Cup comprised two separate football tournaments played in aid of the Lord Provost's Rent Relief Fund in 1921. Held in Edinburgh and Glasgow, both were one-off competitions. Various other tournaments and events were held to help the unemployed in 1921.
The six member clubs (Celtic, Clyde, Queen's Park, Partick Thistle, Rangers, and Third Lanark) of both the Glasgow FA and the Scottish Football League competed in the Glasgow tournament. All six teams were used to playing against each other in city knockout competitions, with both the Glasgow Cup and Glasgow Charity Cup held on an annual basis. The tournament was completed in a month.
