2021–22 FC Admira Wacker Mödling season

The 2021–22 season was the 117th season in the existence of Admira Wacker Mödling and the club's tenth consecutive season in the top flight of Austrian football. In addition to the domestic league, Admira Wacker Mödling participated in this season's edition of the Austrian Cup. Due to a 2017 sponsorship agreement with the Würzburg-based online printing company Flyeralarm, which secured the club's naming rights, Admira Wacker Mödling was officially known as FC Flyeralarm Admira throughout the season.

Despite finishing 11th in the regular season, six points clear of last-place Rheindorf Altach, Admira Wacker struggled in the relegation round, failing to win any of their final five matches. Their relegation was confirmed on the final matchday following a 3–1 defeat to LASK.
