The Flumserberg Ladies Open is a women's professional golf tournament in the LET Access Series, held since 2014 at Gams-Werdenberg Golf Club in St. Gallen, Switzerland.

Originally the tournament was named after its main sponsor, the Association Suisse des Golfeurs Indépendants (ASGI).

In 2023, the tournament's 10-year anniversary, the format changed to "Mätzler Mix", with 36 hole stroke play over Friday and Saturday, followed by three rounds of 9 hole match play on Sunday.
