The Avia Foursomes was a women's foursomes golf tournament contested annually from 1958 to 1989. It was held at Sunningdale Golf Club in its first year but was then played at the Berkshire Golf Club near Ascot, Berkshire. The event consisted of 72 holes of stroke play. From 1958 to 1964 it was called the Kayser Bondor Foursomes and in 1965 Casa Pupo Foursomes before being sponsored by Avia watches from 1966. Avia withdrew their sponsorship after the 1989 event. In 1978 the event was opened up to professionals, although they had to play with an amateur.
