Maria Yuryevna Sharapova (, ; born 19 April 1987) is a Russian former world No. 1 tennis player. She competed on the WTA Tour from 2001 to 2020 and was ranked world No. 1 in singles by the Women's Tennis Association (WTA) for 21 weeks. She is one of ten women, and the only Russian, to achieve the career Grand Slam. She is also an Olympic medalist, having won silver in women's singles at the 2012 London Olympics. Sharapova became the world No. 1 for the first time on 22 August 2005 at the age of 18, becoming the first Russian woman to top the singles rankings, and last held the position for a fifth time for four weeks from 11 June 2012 to 8 July 2012. She won five major titles — two at the French Open and one each at the Australian Open, Wimbledon, and the US Open. She won 36 titles in total, including the year-end championships in her debut in 2004. She also won three doubles titles. Although she played under the banner of Russia with the WTA, she has lived in and been a United States permanent resident since 1994. Sharapova failed a drug test at the 2016 Australian Open, testing positive for meldonium, a substance that had been banned (effective January 1, 2016) by the World Anti-Doping Agency (WADA). On 8 June 2016, she was suspended from playing tennis for two years by the International Tennis Federation (ITF). On 4 October 2016, the suspension was reduced to 15 months, starting from the date of the failed test, as the Court of Arbitration for Sport found that she had committed "no significant fault" and that she had taken the substance "based on a doctor's recommendation… with good faith belief that it was appropriate and compliant with the relevant rules". She returned to the WTA Tour on 26 April 2017 at the Porsche Tennis Grand Prix. Sharapova has been featured in a number of modeling assignments, including a feature in the Sports Illustrated Swimsuit Issue. She has appeared in many advertisements, including those for Nike, Prince, and Canon, and has been the face of several fashion houses, most notably Cole Haan. Since February 2007, she has been a United Nations Development Programme Goodwill Ambassador, concerned specifically with the Chernobyl Recovery and Development Programme.
