The WTA Bayonne was a WTA Tour affiliated women's tennis tournament held from 1989 until 1992 in Bayonne, France. It was also known as the Whirlpool Open, owing to its sponsor in 1991 and 1992.

During the event's first two years there was a total of US$100,000 on offer to players; during the final two years, when it was upgraded from a WTA Tier V to a WTA Tier IV event, the total prize fund was increased to $150,000. The inaugural event was held on indoor hard courts; the final three were played on indoor carpet courts. The tournaments were held in either late September or October.^[1][2][3][4]
