Speaking to US broadcaster ABC ahead of his grandmother the Queen's Diamond Jubilee, Harry said: "I've longed for kids since I was very, very young.
"And so I'm waiting to find the right person, someone who's willing to take on the job."
It is the first time Harry, 27, has confessed to feeling broody.
His brother Prince William also said he and wife Kate were "very keen" to start a family.
The Duke of Cambridge said: "I'm just very keen to have a family, and both Catherine and I are looking forward to having a family in the future."
Asked by ABC's Katie Couric if there was anything else he wanted to share, Prince William laughed: "You won't get anything out of me. Tight-lipped."
Well Harry, as Britain's most eligible bachelor, we're sure you won't have trouble finding the right person...
