While Lord Voldemort is the main antagonist, with he and his Death Eaters bringing the main conflict, many other characters qualify as villains because they bring misery and harm to Harry. These include: the Malfoy family, the Dursley family, dangerous magical creatures, and Ministry of Magic employees like Dolores Umbridge. Of course, Voldemort does place at the top of this pile.
