Ledøje-Smørum Fodbold (LSF, Danish pronunciation: [ˈle̝ðˌʌjə ˈsmɶːʁɔm ˈfoðˌpʌlˀt]) is an association football club based in the town of Smørumnedre, Denmark.

The football department is part of the larger sports club, Ledøje-Smørum Idrætsforening, but operates as its own independent unit with their own board of representatives.

Around 1915, the club is able to assemble a strong team, which participates in tournaments under Sjællands Boldspil-Union (SBU), the local branch of the Danish Football Union (DBU).

Therefore, the home ground was moved to farmer Albrechtsen's field in Lille Smørum, in an area south of Skebjergvej – still under primitive conditions, without changing facilities or showers.

In 1953, in a protest against lack of organisation, a competing club, Ledøje Smørum Idrætsforening, was established, with Jes Dahl Christensen as chairman.
