The 700 member club was founded in March 1921 and played in lower-tier competition until the mid-90s when the footballers advanced for the first time to the Landesliga Bayern-Süd (V).

Ismaning enjoyed its most successful season to date in 1999–2000 when it took the Landesliga title to move up to the Oberliga Bayern (IV) and also captured the Bavarian Cup.

They won the Bayernliga on 21 May 2011 with a 4–1 win at home to SV Seligenporten but declined to apply for a Regionalliga licence and were therefore not promoted.

At the end of the 2011–12 season the club managed to finish in the top nine of the Bayernliga and thereby directly qualified for the new tier four Regionalliga Bayern.

FC Ismaning plays its home fixtures in the Stadion an der Lindenstraße (capacity 5,000).
