If you're referring to the years while he was at Hogwarts, JK never stated specifically if he had a girlfriend, but from what 당신 read from the context, 당신 could assume that Pansy Parkinson was his "romantic interest". If you're referring to who he married, it is Astoria Greengrass. :)
Well I personally think that in his hogwarts life his girlfriend was Pansy Parkinson. Although Pansy was always smothering him he still loved her. I also think that he teased Hermione because he had feelings for her, so Draco probably loved Hermione 더 많이 than anything in the world but, unfortunately, she didn't 사랑 him back. And eventually, Draco went and married Astoria Greengrass. Now Tom Felton (the person who portrays Draco Malfoy) has a real girlfriend too. Her name is Jade Olivia.
The correct 질문 would be who is Draco's *boyfriend* and that would be Harry Potter the famous weirdo himself... I mean, JUST LOOK AT THIS PHOTO!!! Probably one of the best but who am I kidding? I have waaaayyyy too many pictures of them...
