Dennis (born c. 1980) was a Muggle and, in his youth, a member of Dudley Dursley's gang. Dennis, along with the rest of the group, was described as "big and stupid".

During the summer months of 1991, Dennis would go to Dudley's house every day, along with his friends Piers Polkiss, Malcolm and Gordon. This forced Harry Potter to spend as much time as possible out of the house, as they were fond of bullying him.^[1]

Behind the scenes

• Dennis was played by Christopher Rithin in the film adaptation of Harry Potter and the Order of the Phoenix, but his role was uncredited.
• In the gang's appearance in the film version of Harry Potter and the Order of the Phoenix, Dennis is the youth wearing the green shirt on the far left.
• In LEGO Harry Potter: Years 5-7 he does not join his friends teasing Harry because he became too dizzy after riding on the roundabout.

Etymology

The name "Dennis" comes 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.
