Julie Ditty (born January 4, 1979, in Atlanta, Georgia) is an American professional tennis player. Ditty did not have her true WTA breakthrough until 2007, when she reached the semifinals of the Bell Challenge, a result that took her into the top 100 for the first time in her career on November 5, 2007, at No. 91. She beat Alizé Cornet and Vania King before falling to Julia Vakulenko in three sets.
In 2008, Ditty qualified for the Gaz de France tournament in Paris where she lost to the Number 6 seed and former world number 1 Amélie Mauresmo. During the Proximus Diamond Games in Antwerp, she made it through the first round by defeating Alyona Bondarenko, who was seeded eighth, and got to the 2nd round there before falling to qualifier Timea Bacsinszky 7–5 6–4, after having leads in both sets. Her win over world No. 22 Alyona Bondarenko was best-ever career win. In August, Julie defeated Meng Yuan in the first round at Cincinnati, marking her first win in a WTA main draw since Antwerp.
