Over the course of his career, Čilić has won 18 ATP singles titles, including a Grand Slam title at the 2014 US Open. His career-high singles ranking is world No. 3, achieved on January 28, 2018. Čilić first came to international prominence by defeating world No. 2 Andy Murray in the fourth round of the 2009 US Open, and then reaching the semi-finals at the Australian Open a few months later. He was also runner-up at the 2017 Wimbledon Championships and the 2018 Australian Open, losing to Roger Federer both times. Čilić has reached at least quarterfinal in all four major tournaments, and has made it to at least that stage at 13 different Grand Slams. He is known for his fast serves and powerful ground-strokes.
Čilić started to develop his career at a young age; his first steps of tennis started in Bosnia and Herzegovina. His potential was discovered by local hometown coaches who saw him play and encouraged his move to Zagreb for further training. He was soon befriended by his countryman to be Goran Ivanišević, who introduced him to coach Bob Brett. Čilić turned professional in 2005, and ultimately hired Ivanišević as his full-time coach in 2013. Čilić parted ways with Ivanišević in late July 2016, after advancing to the 2016 Davis Cup semifinals.
Marin Čilić was born in Krstine, Međugorje, a town in Herzegovina region of Bosnia and Herzegovina to Herzegovinian Croat parents. He was raised as a Roman Catholic. His father Zdenko was determined that his sons – Marin and older brothers Vinko and Goran – would have the opportunities he lacked in playing sports. When the first tennis courts in the town were built in 1991, Marin and his friends were among the first to play on them. At the recommendation of Goran Ivanišević, in 2004, at the age of 15, Čilić moved to San Remo, Italy to work with Ivanišević's former coach, Bob Brett.
Čilić began playing on the junior ITF circuit in spring 2004. At the start he played on clay courts, winning the La Vie Junior Cup Villach in singles and the Dutch Junior Open in doubles.

At Wimbledon Čilić pulled out before his second round match claiming he had a left knee injury where he was scheduled to play Kenny de Schepper of France. However, a month later it was revealed that Čilić had pulled out due to failing a drugs test in Munich, allegedly for "incautious use of glucose."On September 16, 2013, he received a backdated nine-month ban due to testing positive for the banned substance nikethamide. Čilić claimed that the banned substance was ingested via Coramine glucose tablets bought at a pharmacy by a member of his team, and as a result the independent tribunal believed that he did not intend to enhance his performance. The suspension ran until February 1 2014 and all prize money and points since the positive test including the Munich tournament were null and forfeited. Čilić appealed against this ban to the Court of Arbitration for Sport, who reduced the ban from nine months to four months on October 25. They stated that "the degree of fault committed by the athlete was inferior to that established in the (tribunal) decision and the sanction imposed was too severe in view of the degree of fault". Čilić, whose ranking had dropped to number 47, received an immediate boost as results at the French Open, Queen's and Wimbledon were reinstated.

At the conclusion of the tournament, Čilić reached a career-high ATP ranking of No. 3. He remained at that position for 12 weeks, before being surpassed by Alexander Zverev.

After another two winless tournaments to start the clay court season (at Monte-Carlo and Budapest), Čilić finally broke his slump at the Madrid Masters by winning three consecutive matches against Martin Kližan, Jan-Lennard Struff, & Laslo Đere on the way to the quarterfinals. However, he had to withdraw before his match against Novak Djokovic due to food poisoning. By reaching the quarterfinals, Čilić became one of the few players on the Tour to reach the quarterfinal stage of all nine Masters 1000 tournaments.
