Djokovic and longtime girlfriend Jelena Ristic were wed Thursday in an upscale resort on the Adriatic coast.
Local media say the ceremony was attended by family, friends and guests, but away from the public eye.
After beating Roger Federer in five sets Sunday for his second Wimbledon title, Djokovic dedicated the victory to his fiancee "and our future baby."
Djokovic and Ristic first met in high school. They have been together for more than eight years and are expecting their first child later this year.
Local media reports say resort employees, waiters and staff had to sign confidentiality agreements and were not allowed to use their mobile phones.
