Jana Kandarr (born 21 September 1976) is a German former top 50 professional tennis player.

Her mother Petra Vogt is a former European athletics champion and was Sports Person of the Year in the German Democratic Republic (East Germany) in 1969.

The biggest success of her 10-year-long career was her participation in the Australian Open in 2000, where she made the round of 16, coming through qualifying and winning six three-set matches in a row, before being forced to retire against ninth seed Julie Halard-Decugis.

Kandarr ended her professional career in 2005 but is still playing competitive tennis occasionally in the Bundesliga for TC 1899 Blau-Weiss Berlin.

From the winter semester of 2002/03, she has been studying geoscience and biology at the Humboldt University of Berlin, while living in Berlin-Kreuzberg.
