Professor Abraham Van Helsing is a fictional character from the 1897 gothic horror novel Dracula written by Bram Stoker. Van Helsing is a Dutch polymath doctor with a wide range of interests and accomplishments, partly attested by the string of letters that follows his name: "MD, D.Ph., D.Litt., etc.", indicating a wealth of experience, education and expertise. He is a doctor, professor, lawyer, philosopher, scientist, and metaphysician. The character is best known through many adaptations of the story as a vampire slayer, monster hunter and the arch-nemesis of Count Dracula, and the prototypical and the archetypical parapsychologist in subsequent works of paranormal fiction. Some later works tell new stories about Van Helsing, while others, such as Dracula (2020) and I Woke Up a Vampire (2023) have characters that are his descendants.
