Jürgen Melzer (born 22 May 1981 in Vienna) is an Austrian tennis player. He reached a career-high ranking of No. 8 on 18 April 2011, and a doubles ranking of No. 6 on 13 September 2010. He is the only player on the ATP Tour to be ranked in the Top 10 in both singles and doubles. He is a left-handed tennis player but is right-handed in everyday life. He has a younger brother, Gerald Melzer, who he has played doubles with 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 when he reached the semi-finals of the French Open in 2010. He has also had success in doubles, winning the mens doubles event at Wimbledon in 2010 with Philipp Petzschner and the mixed doubles event at Wimbledon a year later with Iveta Benesova.
He is endorsed by Adidas and Dunlop Sport. Melzer is currently coached by Joakim Nystrom
