Marcos Baghdatis (born 17 June, 1985, Limassol, Cyprus) is a professional Tennis player.

He became the ITF World Junior Tennis Champion in 2003. He joined the ATP professional tour in late 2003. After performing moderately throughout most of 2004, he picked up his form later in that year. He was one of the two players who took a set off his encounter with Roger Federer in the 2004 US Open (The other player was Andre Agassi). Baghdatis then went on a superb run to finish the year with two challenger tournament titles in which he defeated many higher ranked opponents.

2005 began on a low when Baghdatis crashed out of the Chennai Open in the first round. But he redeemed himself in spectacular fashion in his next tournament which was the year's first Grand Slam, the Australian Open. He ousted top-20 player Ivan Ljubicic in the second round and then had a convincing straight set victory over another top-20 player Tommy Robredo in the third round. Unfortunately, he ran into Roger Federer again in the fourth round and lost the match but not before managing to take a set to the tiebreaker.

Baghdatis's playing style is relaxed and smooth, with no apparent technical weakness in any particular area of his game. He also has an exuberant and festive on-court presence that frequently rubs off on to the spectators.

The run of good form for Baghdatis, beginning in late 2004 and continuing through the beginning of 2005, sets him apart as a player to watch out for in the coming months.
