Mark Anthony Philippoussis (born November 7, 1976) is an Australian tennis player. He turned professional in 1994 and as of 2007 resides in Nevada, United States. His background is a combination of Greek and Italian and he is well known for his powerful physique, standing at 6 ft 5 inches and weighing 226 pounds. He has also had a minor career in modelling and starred in the American reality television dating show Age of Love.

Philippoussis was born in Melbourne and educated at Wesley College, also the school of Theo.

Coached by his father, Nick Philippoussis, the right-hander has played tennis since he was six years of age. He was briefly coached by former 1987 Wimbledon champion Pat Cash during his junior years, which ended in an acrimonious split.

In 1994, he finished third in single ranking for juniors. Philippoussis also finished as junior doubles champion with Ben Ellwood in Australia, Wimbledon, and Italy. He turned professional in 1994.

In 1995, at the age of 19, he was the youngest player in the year-end top 50. In 1996, he reached the 4th round of the Australian Open upsetting Pete Sampras in the 3rd round and in doubles with Patrick Rafter. On May 25, 1997, he recorded a personal best 229.0 km/h (142.3 mph) serve in a game he lost to Albert Costa. During the height of his career, Mark was notoriously known as having one of the fastest services in the game.

In 1998, he reached his first Grand Slam final at the US Open losing to fellow Australian Patrick Rafter. On March 29, 1999, he entered the top 10 for the first time and stayed there for 11 weeks. He advanced to the quarter finals at Wimbledon for the second straight year and retired in 2nd set against no. 1 Pete Sampras after having won the first set. He suffered a moderate cartilage tear in his left knee and underwent arthroscopic surgery four days later on July 6. Sampras later remarked that he "dodged a bullet out there." He returned to professional tennis seven weeks later in Indianapolis and lost in his opening match. He did not play again until October 12 in Singapore where he lost in 2nd Round.

He finished 1999 in the top 20. 2000 was the fourth consecutive year in which he finished in the top 20. He reached the 4th round at the Australian Open losing to eventual champion Andre Agassi. He defeated Pete Sampras 8-6 in the fifth set at Roland Garros in a 1st round match but lost in the 4th round. For the third consecutive year, he made it to the quarterfinals at Wimbledon losing again to Andre Agassi. He appeared in his second Olympics, losing in 3rd Round to eventual gold medalist Yevgeny Kafelnikov. He finished 2002 in the top 100 (7th time in 8 years) despite not winning a title. He moved from Miami to San Diego, California area in September 2002.

Philippoussis has always claimed to be proud of representing his country in Davis Cup, but personal differences with John Newcombe and Tony Roche interfered with his commitment early in his career. Despite several highly publicised feuds, Mark played a large part in giving Australia their 27th Davis Cup triumph - second only to the United States with 31 - but it was their first since 1986. In 1999 Mark defeated Cedric Pioline, 6-3, 5-7, 6-1, 6-2 in front of a boisterous French crowd in Nice.

Injuries plagued Mark's availability for Davis cup and was the cause of a public rift between team-mates Patrick Rafter and Lleyton Hewitt. Rafter publicly accused Philippoussis of 'jerking' the team around after he withdrew from a Davis Cup tie in late 2000. Philippoussis said Rafter was 'ill-informed' and upset by the lack of support and understanding from his team-mates.

Knee surgeries forced Philippoussis out of Davis Cup till February 2003. By then Pat Rafter had retired, and John Fitzgerald and Wally Masur were the new Davis Cup captain and coach. The impact of these changes was instantly recognised as team harmony was at its highest throughout the year. Mark Philippoussis once again sealed victory for Australia in the Melbourne Final against Spain. Mark beat Spain’s Juan Carlos Ferrero in a 7-5 6-3 1-6 2-6 6-0 battle. Mark suffered a pectoral tear at the end of the second set which caused him to lose the third and fourth sets. Displaying spectacular courage, Mark regrouped in the fifth set, and in immense pain, trounced Ferrero 6-0.

After three knee operations and a protracted comeback, Philippoussis avowed a new seriousness to his sport. He made himself available regularly for Davis Cup, hired a new physical trainer, and took up surfing as his new recreation. It seemed to work, as he made the 2003 Wimbledon final, finally losing to Roger Federer 7-6(7/5), 6-2, 7-6(7/3) http://news.bbc.co.uk/sport1/hi/tennis/wimbledon_2003/3049382.stm.

During a 2003 Wimbledon tennis match against Andre Agassi (6-3, 2-6, 6-7 (4-7), 6-3, 6-4), he set a new Australian tennis record of 46 aces served in a match, three aces short of the overall ATP Tour record then held by Richard Krajicek.

Philippoussis broke a two year singles title drought by winning the Shanghai Open in 2003. On November 30, 2003, he defeated Juan Carlos Ferrero of Spain to win the fourth match of the Davis Cup final in Melbourne, securing the title for Australia. This victory in front of his home crowd won him a place in the affections of the Australian sporting public which some of his behaviour in earlier years — including inconsistent Davis Cup appearances — had put in jeopardy.

The honeymoon period with the Australian public, however, did not last. 2004 proved a disastrous year in terms of his tennis career and public profile. After shouldering most of the blame for losing Australia's Davis Cup tie with Sweden with an unexpected below par performance, Philippoussis struggled through to the Wimbledon fourth round in June 2004.

From Wimbledon in June until the end of the season in October, he failed to win a single ATP tennis match and finished with one of his lowest ever rankings since turning professional in 1994.

In October 2004, a much publicized affair with Delta Goodrem had soured and seriously damaged his standing after newspapers alleged that he had dated Paris Hilton while with Goodrem. In March 2005, he became engaged to Miami-born actress and model Alexis Barbara. The Age reported the pair had split in July 2006, but Philippoussis has denied this to Australian tabloid New Idea; they did split some time before he began filming The Age of Love.

He confirmed to Sydney's Daily Telegraph on August 23, 2006, that he "parted ways with" his father as his coach and rehired Peter McNamara in an attempt to revive his career.

After some controversy over his wildcard selection firstly after a disappointing 2006 Australian Open, Philippoussis made more headlines when he again earned entry into the 2006 Wimbledon. He was defeated in the 2nd round.

Leading into the Campbell's Hall of Fame Championships as a wildcard, his record was a modest 6-7. He had a fantastic run in the tournament, getting all the way to the final, where he defeated Justin Gimelstob in straight sets to claim his first title in almost three years.

Philippoussis, currently ranked #114, lost to Rafael Nadal as a wildcard entry in the 1st round of the 2006 US Open.

The Australian Davis Cup team lost against Argentina in an unpredictable 5-0. On Friday (September 22nd) Mark was defeated by David Nalbandian 6-4 6-3 6-3, in the first match of the series.

Philippoussis has played in a series of Challenger tournaments since the Davis Cup semifinals. Philippoussis won the Calabasas tournament, defeating Amer Delic 6-7(4-7), 7-6(7-4), 6-3 in the final.

Philippoussis beat Russian Dmitry Tursunov 6-4 7-6 at the 2007 Hopman Cup. However, during his second match against Jerome Haehnel, he was forced to retire after hyperextending his knee. An MRI showed that he had torn cartilage in his knee, forcing him to miss the Australian Open.

Philippoussis stars as the bachelor in the reality television dating show Age of Love on the NBC television network, beginning 18 June, 2007. The show centres around women in or near their 40s and women in their 20s competing for his affection. At first this 6'5" heartthrob was shocked at the ages of the "Cougars" as the older women are called. The "Kittens", the younger women, seemed to be very cocky when they heard they were going against the older women. The final dates occurred in his hometown of Melbourne, Australia. In the end, Mark chose Amanda (the 25-year old Nashville Predators dancer) because it "wouldn't work out" with Jen, the 48-year old assistant to Jerry Buss.
