Mario Ančić (Croatian pronunciation: [mâːrio âːntʃitɕ]; born 30 March 1984) is a Croatian former professional tennis player who currently works as a private equity vice president in New York City. He won three singles titles and five doubles titles on the ATP Tour. Ančić's career-high singles ranking came in 2006, when he reached world No. 7. Ančić helped Croatia to win the 2005 Davis Cup and claimed a bronze medal for the country at the 2004 Athens Olympics, in men's doubles partnering Ivan Ljubičić.
As a teenager making his major debut at the 2002 Wimbledon Championships, he defeated seventh-seeded Roger Federer. His best performance at the majors came at the 2004 Wimbledon Championships, when he reached the semifinals. During 2007 and 2008, infectious mononucleosis and minor injuries forced him to miss many major events, and his ranking dropped from No. 9 in January 2007 to No. 135 in January 2008.
