The royal has found himself under scrutiny after several photos of him in the nude at a party in Las Vegas surfaced.
He has now deleted what is said to be his secret Facebook account under the name Spike Wells, on the advice of his private secretary Jamie Lowther-Pinkerton.
Buckingham Palace officials are allegedly worried that photos of the prince taken during a holiday on Sir Richard Branson's private Necker Island prior to the Las Vegas incident may leak after they were published by a friend of the royal, reports the Daily Mail.
Tom Inskip and Arthur Landon, two friends of Prince Harry, have also apparently deleted their accounts to prevent people seeing pictures of the royal.
Prince Harry has since returned to the UK, where brother Prince William is reportedly "not impressed" with his behaviour.
