The Luxembourg Open, last sponsored by BGL, was a women's tennis tournament held in Kockelscheuer, Luxembourg. Held since 1991, the tournament was an exhibition event (winners including Novotná, Navratilova and Sabine Appelmans) until 1995. After that, it became a WTA Tier III tournament, which it remained until 2004. In 2005, it was promoted to Tier II, marking the first such event to be held in Luxembourg. In 2008, the tournament was relegated to a Tier III event, before it became an International Series tournament in 2009.
Kim Clijsters of Belgium holds the record of most singles wins: 5 (1999, 2001, 2002, 2003, 2005). No other player has won more than twice.
