Harry and Hermione never kiss, but Ron and Hermione do.
Edit: Once, after the Triwizard Tournament Hermione kissed Harry on the cheek. 188.8.131.52 05:29, March 21, 2010 (UTC)
-Edit again: Hermione and Harry do kiss but it's an illusion created by the necklace horcrux to try to distract Ron when he tries to destroy it. Other than that, no. Hermione loves Ron, and Harry is just a friend.-
Harry and Hermione's love extends only to brotherly/sisterly love. The riddle-harry and riddle-hermione kiss, and once hermione kisses harry on the cheek but its more of family love
