Martina Navratilova (born October 18, 1956) is a Czech American and former Czechoslovak tennis player and a former World No. 1 (List of WTA number 1 ranked players). Billie Jean King said about Navratilova in 2006, "Shes the greatest singles, doubles and mixed doubles (Types of tennis match) player whos ever lived."

Navratilova won 18 Grand Slam (Grand Slam (tennis)) singles titles, 31 Grand Slam womens doubles titles (an all-time record), and 10 Grand Slam mixed doubles titles. She reached the Wimbledon (The Championships, Wimbledon) singles final 12 times, including 9 consecutive years from 1982 through 1990, and won the womens singles title at Wimbledon a record 9 times. She and King each won 20 Wimbledon titles, an all-time record. Navratilova is one of just three women to have accomplished a career Grand Slam in singles, womens doubles, and mixed doubles (called the Grand Slam "boxed set"). She holds the open era (History of tennis#Open era) record for most singles titles (167) and doubles titles (177). She recorded the longest winning streak in the open era (74 consecutive matches) and three of the six longest winning streaks in the womens open era. Navratilova, Margaret Court, and Maureen Connolly share the record for the most consecutive Grand Slam singles titles (six). Navratilova reached 11 consecutive Grand Slam singles finals, second all-time to Steffi Grafs (Steffi Graf) 13. In womens doubles, Navratilova and Pam Shriver won 109 consecutive matches and won all four Grand Slam titles in 1984. They also tied Louise Brough Clapps (Louise Brough Clapp) and Margaret Osborne duPonts (Margaret Osborne duPont) record of 20 Grand Slam womens doubles titles as a team.

Originally from Czechoslovakia, she was stripped of her citizenship when, in 1975 at the age of 18, she asked the United States for political asylum and was granted temporary residency. At the time, Navratilova was being told by the Czechoslovakian Sports Federation that she was becoming too Americanized and that she should go back to school and make tennis secondary. Navratilova became a US citizen in 1981, but on January 9, 2008, she had her Czech citizenship restored. She stated she has not renounced her American citizenship nor does she plan to do so and that the restoration of her Czech citizenship was not politically motivated. On the other hand, Navratilova was quoted in 2007 as being ashamed of the US under President George W. Bush.

Navratilova is a member of the Laureus World Sports Academy. She also serves the Health and Fitness Ambassador for AARP in an alliance created to help AARPs millions of members lead active, healthy lives.
