Which Harry Potter character is the only child of James and Lily Potter?

Harry Potter is the only child of James and Lily Potter.

James and Lily Potter were members of the original Order of the Phoenix and opposed Lord Voldemort during the First Wizarding War. Their son Harry was born on 31 July 1980, according to the series’ established timeline.

Voldemort attacked the Potter family at Godric’s Hollow when Harry was an infant. James and Lily were killed, but Lily’s sacrifice protected Harry from the killing curse. Harry therefore survived with the lightning-shaped scar that became one of his defining features.

Harry’s family situation is sometimes mixed up with the larger group of children connected to the prophecy about Voldemort. Neville Longbottom was also born at the end of July 1980 and was considered a possible subject of the prophecy, but he is not James and Lily Potter’s child. Harry is their sole child.
