Defending champion Peter Norfolk defeated David Wagner in the final, 6–3, 3–6, 6–3 to win the quad singles wheelchair tennis title at the 2009 US Open.
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.
