Karolina Šprem (born October 25, 1984 in Varaždin) is a Croatian tennis player. Her current WTA ranking is #209 (as of December 24, 2007).
She has won 8 titles (7 singles, 1 Doubles) all at the ITF level. She has not won any titles on the WTA Tour. Career highlight is a quarterfinal appearance at Wimbledon in 2004 where she controversially defeated two time champion, four time finalist and then world No. 8 Venus Williams in the second round (lost to Lindsay Davenport in QF). The umpire of her match against Venus Williams awarded her an extra point in the second set tie break. He was relieved of his duties after the end of the match.
Her career seemed to be promising, on her first two WTA-tournaments she reached the finals, however sometime in late 2004 her form saw a downward curve. She began training with a controversial Borna Bikic, who at that time was the boyfriend of Jelena Dokic. Since then she hardly won a match. In late 2007 Sprem announced a permanent split from Bikic, and returned to her old coach. Still, she has to cope with a serious elbow injury. She hopes to return to the tour for the clay court season in 2008.
