Milos Raonic ( /ˈmiːloʊʃ ˈraʊnɪtʃ/ MEE-lohsh ROW-nich;Serbian: Милош Раонић, Miloš Raonić [mîloʃ râonitɕ]; born December 27, 1990) is a Canadian professional tennis player who lives in Thornhill, Ontario, Canada.

Born in what is now Podgorica, Montenegro, Raonic moved to Canada with his family at the age of 3. He speaks his native Serbian and English. Raonic is Canada's highest ATP ranked male singles player since computer rankings began in 1973. He qualified for his first grand slam event at the 2010 U.S. Open. In 2011 he rose from World No. 152 to No. 37 in a month, after he reached the fourth round of the Australian Open and won his first ATP title at the 2011 SAP Open. Raonic, who prefers to play on hard courts, plays an all-court game but is most notable for his serve, which is powerful and accurate. Since late 2010 he has been coached by former Spanish pro player Galo Blanco in Barcelona.

Raonic's first ITF-sanctioned junior tennis event was the qualifying draw for the Canadian ITF Group 4 Championships in October 2003, where he lost in the first round to fellow Canadian Kirill Sinitsyn 6–7, 3–6. His next junior circuit action was a year later at the Canadian ITF Championships 1 event, where he lost in the first round of the main draw 4–6, 4–6 to compatriot Peter Marrack. In doubles at the same event he and partner Sheharyar Wali, also Canadian, reached the second round.
