It took place at the Milan Gale Muškatirović complex in Belgrade, Serbia, from May 2 through May 10, 2009.
The singles draw was headlined by the tournament's host, Association of Tennis Professionals (ATP) No. 3, 2008 Tennis Masters Cup, Dubai winner and recent Miami, Monte Carlo and Rome runner-up Novak Djokovic from Serbia. Other featured stars included reigning Nottingham champion Ivo Karlović, and Gstaad and Umag finalist Igor Andreev.
