The Linz Open, formerly sponsored by Generali Gruppe, is a women's tennis tournament held in Linz, Austria. It is played on indoor hardcourts.
The inaugural event took place in 1987 in Wels, Austria and was organized by the ITF as a $10,000 tournament. Starting 1991, it has been organized in Linz as a WTA Tour event, initially on the Tier V-level. In 1993 it got promoted to Tier III-level, and since 1998 it was organized as a Tier II-tournament. In 2009, it was designated as a WTA International Tournament and subsequently WTA 250 in 2021 with the change in tournament tier nomenclature. In 2023, the scheduling change in the WTA calendar saw the tournament being held in February instead of October as in the past editions. In 2024, the tournament was once again upgraded to WTA 500 level event.
Past champions of the tournament include former world number ones Lindsay Davenport, Justine Henin-Hardenne, Amélie Mauresmo, Maria Sharapova and Ana Ivanovic. More recent champions include Petra Kvitová, Victoria Azarenka, Angelique Kerber, Karolína Plíšková and Dominika Cibulková.
