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 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.
