Differdange 03 was formed in 2003 as an amalgam of two clubs from the city of Differdange: FA Red Boys Differdange and AS Differdange. When the clubs merged, in time for the 2003–04 season, Red Boys was languishing in the bottom half of the Division of Honour, while AS was in mid-table position in the third tier of Luxembourgian football. The new club took Red Boys league position, and was promoted back into the National Division in the 2005–06 season, when the top division was expanded from twelve clubs to fourteen.
Red Boys Differdange had previously been one of the largest and most successful teams in Luxembourgian football, having won the Luxembourg Cup more times than any other team (16). During the 1920s and 1930s, Red Boys competed with Spora Luxembourg for dominance of Luxembourgian football. Red Boys was the more successful of the two, and won thirteen trophies in as many years between 1923 and 1936. Despite the staunch competition (Spora won 8 trophies in the same period), this record has never been matched.
In the 2011-12 UEFA Europa League Differdange 03 progressed to the 3rd qualifying round of the competition after they eliminated Levadia Tallinn 1–0 on aggregate, one of the club's most famous European victories and one of the most historic victories for a club from Luxembourg has ever had in European Competitions. In the 3rd qualifying round they met Olympiakos Volou and lost 3–0 in both legs, 6–0 on aggregate. However, as Olympiakos Volou was presumably involved in a corruption case, UEFA decided on 11 August 2011 that Differdange would progress to the Play Off Round and meet Paris Saint-Germain, the furthest a club from Luxembourg has reached in European competitions.
In June 2012, after a pretty bad season in BGL League (4th), FCD03 change coach, the exemption of Paolo Amodio reported the experience of Michel Floch'moan who is familiar in BGL League, because with the F91 Dudelange and with Jeunesse Esch he win multiple championships in Luxembourg.
The 5 and 12 July 2012, FCD03 won against NSI for the first round of qualifying for Europe League with 3–0 and 0–3, with a total of 6 goals in two games. In the second round, FC Differdange 03 will meet Belgian club KAA Gent on Thursday 19 July 2012.
