The 16-year-old right-back has put pen-to-paper on a three-year deal.
The youngster made history in our 2-0 win over St Johnstone becoming the youngest player to make his First Team debut for the Club.
Aged just 16 years and 44 days, he is also fourth on the all-time record list of youngest players to feature in the Scottish top-flight.
Whittaker became part of Hibs’ pre-Academy playing at Under-10s, whilst still playing for Spartans, before signing his first registration with the Club at Under-11 level.
The born and bred Hibee has impressed in the Club’s Academy ever since, rising through the Club’s youth ranks, and going on to represent his country – Scotland – at Under-16 and Under-17 level.

On Whittaker’s new deal, Academy Director Gareth Evans commented: “First and foremost, Rory’s contract extension is very well deserved. Throughout his years in the Academy, he’s worked hard to give himself the best possible chance of succeeding.
“We were delighted to see him make his debut, and make history with Hibs, but making your debut as a young player is always the easier part. For him now, the challenge is to keep working hard and pushing himself to try and earn another chance.
“He has to stay humble and keep working with the same determination and desire to ensure he meets his potential.
“The opportunity that Rory received also shows that the Manager is willing to give young players a chance, which is really encouraging for the Academy. Our young players know that if they work hard, continue to develop, and impress, then they may be given that opportunity.”
