The Ernst-Happel-Stadion is a football stadium in Vienna, Austria. The Ernst Happel Stadium is the largest football stadium in Austria. It is the home of the Austrian national football team. Club football matches are limited to the Austrian cup final and international competitions with one of Vienna's top clubs, FK Austria Wien and SK Rapid Wien, as their homegrounds are too small for UEFA Champions League and UEFA Cup matches. Local derbies between FK Austria and SK Rapid have also been played in the stadium. In 2014, it became the official homeground of SK Rapid Wien because their stadium was being rebuilt.
