Ivan Ljubičić ([ˈiʋan ˈʎubitʃitɕ], born March 19, 1979) is a Croatian tennis player. His career-high ATP Entry ranking was No. 3, and his current Entry list ranking is No. 23 (as of March 2008).
Tall and powerfully built, he is noted for his strong serve and has achieved his best results in indoor tournaments played on carpet or hardcourt. He uses a one-handed backhand and often plays from the baseline. Ljubičić is using the Head Microgel Extreme Pro Racquet, after using the Babolat Pure Drive for most of his professional career.
Ljubičić currently serves as the ATP Player Council president, and has strongly voiced his opinion on many issues, such as the possible downgrading of current Masters Series tournaments in Monte Carlo and Hamburg.
Ljubičić and Mario Ančić are the only doubles team to ever defeat Bob and Mike Bryan in Davis Cup history. Ljubičić helped Croatia win the 2005 Davis Cup, where they triumphed over the Slovakian Davis Cup team in the final.
