Harry Edward Melling was born on 17 March 1989 in London, England. He studied at the London Academy of Music and Dramatic Art.
In his early career, Melling performed in stage productions of The Provoked Wife, King John, Antigone, and Plenty. He appeared in five of the Harry Potter films as Harry Potter's spoiled cousin, Dudley Dursley. He was first cast in the role at age 10, in 1999, and played the character until 2010 and his appearance in Harry Potter and the Deathly Hallows
In 2009, Melling starred in a revival of Mother Courage and Her Children at the Royal National Theatre. He appeared in "The Sorcerer's Shadow", an episode of the BBC television series Merlin, playing a young warlock who intends to use magic to help him win Camelot's legendary tournament. He also played Robert Brown in the BBC television series Just William. In 2009, it was announced that Melling had lost so much weight since his last appearance in Harry Potter that he was now "unrecognisable". The role of Dudley was almost recast for Harry Potter and the Deathly Hallows – Part 1, but Melling was able to reprise the part by wearing a fat suit. He said of the change, "I can now shed the child actor thing, like the fat, and start a new career, because no one sees me as Dudley."
