Admira Wacker is an Austrian professional football club based in Maria Enzersdorf, a town in the Mödling District of Lower Austria.

After the Anschluss in 1938, Admira played for several seasons in the Gauliga Ostmark, one of the top-flight regional leagues created through the reorganization of German football under the Third Reich.

The post-war period led to a slow, but steady decline due to lack of funds to buy more competitive players.

The revelation of financial scandals within NEWAG/NIOGAS in the late 1960s led to an abrupt end of the steady flow of funds and brought the club onto the brink of administration, which would narrowly be avoided.

However, after the creation of Admira-Austria was declined twice, Admira eventually began talks with SC Wacker Vienna, which were successfully concluded in 1971.

A fifth relegation in 1971, combined with financial and stadium problems, eventually led to a merger with Admira, forming FC Admira/Wacker Vienna.

Playing most of its existence in second- and third-tier leagues since then, the club enjoyed three brief stints in the top division during the 1952–53 and 1987–88 seasons as well as between 1992 and 1995 before eventually merging with Admira/Wacker in 1997.
