Caroline Maes (born 9 November 1982) is a former Belgian tennis player.

The highest place she ever achieved in the WTA rankings in singles is 151st on 28 May 2007.

Her last and most important ITF title was at the $100k tournament in Rome, on 19 May 2007, defeating Yuliya Beygelzimer and Stéphanie Cohen-Aloro on her way to the final, where she beat former top-50 player Marta Marrero from Spain.

In 2006, she also made it to the round of the last 16 in doubles at the Miami Open, together with Kim Clijsters.

She made herself unavailable for selection in Fed Cup tie against China in 2007, because she wished to attend the wedding of Clijsters and American basketball player Brian Lynch that week-end (14 July 2007) instead.
