The Austrian Open is a men's professional golf tournament on the European Tour.

It was founded in 1990, and was a European Tour event for seven straight years up to 1996, being held under a variety of names due to regular changes of title sponsor.

In 2012, it was announced that the Austrian shopping community Lyoness and its affiliated Greenfinity foundation would be the title sponsors for three seasons.

Players that failed to play within these time limits incurred a one-shot penalty, which was added to their score for that hole.
