The 2005–06 Austrian Cup (German: ÖFB-Cup) was the 72nd season of Austria's nationwide football cup competition. It started on July 26, 2005 with the first game of the preliminary round. The final was held at the Ernst-Happel-Stadion, Vienna on 9 May 2006.
The competition was won by Austria Vienna after beating Mattersburg 3–0. Due to Austria Vienna qualifying for European competition through winning the Bundesliga, Mattersburg qualified for the second qualifying round of the 2006–07 UEFA Cup as cup runners-up.[1]
The Preliminary Round involved 60 lower league clubs from all regional federations. Thirty games were played between July 26 and August 15, 2005, with the winners advancing to the first round.
