"Hiya, Harry! Where are you running off to? It's end of term! No classes!"
—Dennis talking with Harry in the Library[src]

Dennis Aldermaston was a Ravenclaw student at Hogwarts School of Witchcraft and Wizardry in the 1990s. He was usually seen spending time at the Library during the 1996-1997 school year. Preferring to work with Rubeus Hagrid, Dennis didn't like to study. His hero was Gilderoy Lockhart. In 1996 he wanted a new broomstick, which he hoped to receive from his mother at Christmas. At some point in his life he used Skiving Snackboxes.


  • From 'Denys' or 'Denis', the medieval French forms of 'Dionysius'. Saint Denis was a 3rd-century missionary to Gaul who was beheaded in Paris. He is credited with converting the Gauls to Christianity and is considered the patron saint of France. This name was common in France during the Middle Ages, and it was imported by the Normans to England. It is now regularly spelled Dennis in the English-speaking world.
  • "Aldermaston" is a rural village, civil parish and electoral ward in Berkshire, South East England.
