The ILTF Women's International Grand Prix Circuit was one of the worldwide top-tier tennis tours for women founded in 1971 as the ILTF Women's Grand Prix.
[1] It was administered by International Lawn Tennis Federation (ILTF).

In 1976 its last remaining ten events were absorbed into a new women's tour called the Colgate International Series circuit (eventually becoming the Toyota International Series circuit).
