Betty Flippina Stöve (born 24 June 1945) is a Dutch former professional tennis player.

A virus, complicated by a malfunctioning thyroid gland, forced Stöve out of tennis for an 18-month period in the late 1960s.

Stöve's best grand slam singles performance was at the 1977 Wimbledon where she reached the final beating fellow doubles partner Martina Navratilova en route in the quarterfinals, and Sue Barker in the semi-finals preventing an all-England final.

[citation needed] Later that year Stöve was also a semifinalist at the 1977 US Open, losing to Chris Evert.

Notable players she beat in singles include Martina Navratilova, Evonne Goolagong, Sue Barker, Maria Bueno, Virginia Ruzici, Tracy Austin, Kerry Reid, Billie Jean King, and Claudia Kohde-Kilsch.

One notable player she was never able to beat was Chris Evert, to whom she lost on every one of the 10 occasions they played.

She won two women's doubles championships with Billie Jean King and two with Wendy Turnbull.
