Jiske Griffioen and Vergeer were the defending champions, but did not participate together. Griffioen partnered Aniek van Koot, but was defeated in the semifinals by DiToro and Gravellier.
The event was not held in 2008 due to a schedule conflict with the 2008 Summer Paralympics, an issue that would continue to affect US Open wheelchair tennis until 2021.
