Christian Peter Coulson is an English actor known for playing young Tom Marvolo Riddle (Lord Voldemort) in the 2002 fantasy film Harry Potter and the Chamber of Secrets.

He was a member of the UK's National Youth Music Theatre from 1990 to 1997, and went on to the University of Cambridge, where he received a degree in English from Clare College in 2000.

[citation needed] Coulson gained worldwide attention and popularity for his role in 2002's Harry Potter and the Chamber of Secrets, in which he portrayed a 16-year-old Tom Riddle, even though he was 23 at the time.
