Valerie Jean Bradshaw (née Ziegenfuss; June 29, 1949) is an American former female professional tennis player.

She is most famous for being one of the Original 9 with eight of her fellow players,[1] who rebelled against the United States Tennis Association in 1970.

She won a bronze medal in doubles in the 1968 Olympics in Mexico City with Jane Bartkowicz.

[3] The publisher Gladys Heldman, founder of World Tennis magazine, offered $5,000 of her own money, which enabled the players to negotiate their own contracts.

Ziegenfuss and the other players, including Billie Jean King and Rosie Casals, signed $1 contracts in the summer of 1970 and formed the Virginia Slims Circuit.
