Jürgen Melzer, Austrian tennis player
Jürgen Melzer (born 22 May 1981) is a former Austrian professional tennis player. He reached a career-high singles ranking of world No. 8 in April 2011, and a doubles ranking of world No. 6 in September 2010. He has a younger brother, Gerald Melzer, with whom he played doubles in several tournaments.

In 1999, he won the boys' singles event at Wimbledon. For many years he was known as one of the best players on the tour not to have progressed past the third round of a Grand Slam event. He ended this streak by reaching the semifinals of the 2010 French Open, losing to Rafael Nadal after coming from two sets down to defeat Novak Djokovic in the quarterfinals. As of July 2021, he remains the only person to defeat Djokovic from two sets to love down. He has also had success in doubles, winning the men's doubles event at the 2010 Wimbledon Championships and the 2011 US Open with Philipp Petzschner, as well as the mixed doubles event at 2011 Wimbledon Championships with his then future (and later ex-) wife Iveta Benešová.
