WTA Swiss Open
The Ladies Open Lausanne is a women's professional tennis tournament which is currently played in Lausanne but has played in a number of locations in Switzerland. The event was called the WTA Swiss Open from 1899–1994, and was played on outdoor clay courts. The tournament underwent a name change in 1986, when it was titled the European Open until its discontinuation. It formed part of the Women's Tennis Association (WTA) Tour. When the WTA introduced the tiering format to its circuit, the event gradually moved up, from being a Tier V in 1988–1989, a Tier IV from 1990–1992, and a Tier III for its remaining years. The WTA announced that the tournament would return in Gstaad as a clay event on the 2016 Tour, replacing another clay court event held in Bad Gastein.

Four Swiss players won the event: Viktorija Golubic in 2016 as well as Manuela Maleeva (who formerly represented Bulgaria) in 1991 won the singles, and Xenia Knoll (in 2016) as well as Christiane Jolissaint won the doubles, the latter on three occasions: 1983, 1984, and 1988. Maleeva holds the record, along with Chris Evert, for most singles wins; both players won the event three times, and Maleeva finished runner-up a further three occasions.
