Paul Dummett has signed a six year deal and Joe Kinnear takes the credit.
Director of football, Joe Kinnear: "We're delighted that Paul has committed his long term future to the club.
"In reality this was never in doubt as we wanted Paul to stay and as a Geordie Paul made it clear that the only place he wanted to play was Newcastle United - it was just a question of finding the right deal for both parties which we have managed to do.
"It's vitally important that we give young talent the platform to develop a career at Newcastle United and that we retain and develop the region's best players.
"Paul has been given a great opportunity with us and he's grasped it and performed well in the first team during pre-season and in recent games.
"We hope that Paul will follow in the footsteps of current players Tim Krul, Steven Taylor and Shola Ameobi, who have come through the Academy and contributed hugely to this club like many others before them.
"It confirms our belief that there is local talent out there for us to identify and nurture through the club and that our strategy in respect of this can - and will - bear fruit.
"Paul's achievement should give encouragement to our Academy to keep up the great work and also sends a strong positive message to young local players that if you are good enough then there will be opportunities at this club."
