The Serbia Open (Template:Lang-sr) was an ATP World Tour 250 series men's tennis tournament held in Belgrade, Serbia and played on outdoor clay courts. The event was held for the first time in 2009, from May 4–10. It was the first for Serbia, as the country never before hosted an Association of Tennis Professionals or a Women's Tennis Association tournament.
Andreas Seppi was the event's last singles champion, having won the tournament in 2012.
The tournament was owned and run by the family of Novak Djokovic, who through their company Family Sport purchased the ATP Tour date from the organizers of the Dutch Open in 2008, then arranged with the local city of Belgrade authorities for the plot of land where the venue was built, and convinced the Serbian government under prime minister Mirko Cvetkovi? to support the event through state-owned enterprises, primarily Telekom Srbija. At the time of their purchase in 2008, Djokovic was the #3 player in the world having won his first Grand Slam title earlier that year.
Djokovic's uncle Goran was the tournament director from its inception, until he resigned the post in late May 2012, a month after the tournament's 2012 edition. Djokovic won the tournament twice, in 2009. and 2011.
In 2013, Serbia Open was replaced on the ATP schedule by the newly established Power Horse Cup in Düsseldorf.
