Karen Krantzcke (1 February 1946 – 11 April 1977) was an Australian female tennis player who achieved a World Top Ten singles ranking in 1970. In her short career, she made the quarterfinals or better at each of the four Grand Slam championships. She also assisted Australia to victory in the Federation Cup.
Krantzcke's most successful season came in 1969/70. After reaching the US Open quarterfinals, she reached the semifinals at the Australian Open and the French Open and then reached the quarterfinals at Wimbledon. At these tournaments, she upset highly ranked players like Virginia Wade, Françoise Dürr, and Judy Tegart Dalton.
On returning to the tour, she was never able to get back to her best form. She continued to do well in her home Australian championship and reached the semifinals for the second time in 1977.
While playing on the Challenger circuit in the USA in 1977, Krantzcke suffered a heart attack while jogging. In response to her untimely death, the WTA instituted the Karen Krantzcke Sportsmanship Award which is still awarded annually to a female professional tennis player.
