Jelena Dokic (Serbian: Јелена Докић, romanized: Jelena Dokić; .mw-parser-output .IPA-label-small{font-size:85%}.mw-parser-output .references .IPA-label-small,.mw-parser-output .infobox .IPA-label-small,.mw-parser-output .navbox .IPA-label-small{font-size:100%}pronounced [jɛ̌lɛna dokit͡ɕ]; born 12 April 1983) is an Australian tennis commentator, studio analyst and former professional player. Her highest ranking as a tennis player was world No. 4, in August 2002. She won WTA Tour events on all surfaces during her career.
In the 1999 Wimbledon Championships the 16-year-old Dokic achieved one of the biggest upsets in tennis history, beating Martina Hingis 6–2, 6–0 in the first round. This remains the only time the women's world No. 1 has ever lost to a qualifier at Wimbledon. Dokic went on to reach the quarterfinals of that competition, only her second Grand Slam championship.
Dokic rapidly ascended through the rankings after her Wimbledon breakthrough, but her time in the world elite was beset by off-court struggles. Her relationship with her outspoken father and coach Damir Dokić, on whose advice she switched allegiance to the Federal Republic of Yugoslavia in November 2000, was the subject of much media speculation over many years. She switched back to Australia in 2005. Dokic made a serious return to tennis in 2008 and finished 2009 back in the WTA top 100, but thereafter struggled badly with form and injuries, and ceased playing professionally in 2014.
She wrote of physical and mental abuse by her father in her 2017 autobiography Unbreakable. In November 2024, a feature-length documentary film based on the book, titled Unbreakable: The Jelena Dokic Story, was released in Australian cinemas.
