The club is best known for its football section,Mjøndalen IF Fotball, who has won theNorwegian Cup three times,1933,1934 and1937 and finished in second place in Norway'stop tier twice.

As runners-up in the1968 Norwegian Cup, Mjøndalen men's football team represented Norway in theEuropean Cup Winners' Cup in the following1969–70 season. They were eliminated in the first round byCardiff City who defeated Mjøndalen 12–2 on aggregate. After being promoted to thetop division in 1971, Mjøndalen regularly played on the top-tier of Norwegian football in the 1970s and 1980s, and finished second in 1976 and 1986. Finishing runners-up in the league qualified them to represent Norway in theUEFA Cup the following season.

The last round of the 1976 season saw Mjøndalen beatSK Brann, a result which would have awarded them the league title ifLillestrøm SK had lost their game — which they did not. However, Mjøndalen's silver medals saw the team qualify for the1977–78 UEFA Cup, where they lost the first round againstBayern Munich 0–12 on aggregate. After Mjøndalen's second silver medals in the 1986 league season, they were relegated the following season and were not promoted back to the top level until1992.
