The 2007 J&S Cup was a Tier II event on the 2007 WTA Tour that ran from April 30 - May 6, 2007. It was held in Warsaw, Poland, and was the 12th year that the event was staged. Justine Henin won her second Warsaw title and third overall of the year after other victories in Dubai and Doha.
The event was also Kim Clijsters' last professional tournament before taking a break from the sport to start a family. The Belgian lost in the second round to qualifier Julia Vakulenko, and just a few days after announced her retirement from professional tennis. She would eventually return to the sport in 2009 after giving birth to a daughter in 2008.
