The 22-year-old has been part of the club's Elite Development group for the past two seasons, and will continue in the programme for the first part of the coming campaign before moving to a full pro-contract.
The lock forward will thus follow in the footsteps of Stuart Hogg and Finlay Gillies, both of whom have emerged from the Elite Development programme to claim full contracts this season.
Campbell has already made a positive impression in the Warriors first XV, scoring a crucial try in the historic away win over reigning European champions Leinster in the RDS last September and registering a further five RaboDirect PRO12 appearances up to now.
This fresh contract will allow Campbell to maintain and enhance his lifelong link with the game in the west of Scotland.
The 6ft 7in customer received his grounding at Allan Glen's, Cartha Queens Park and Glasgow Hawks, before coming into the Warriors fold in the summer of 2010.
Campbell today declared himself "delighted" to be prolonging his attachment to the club, telling www.glasgowwarriors.org: "As a proud Glasgow boy, it was always my ambition to represent the region as a professional player, and I've loved every minute of my involvement so far.
"It's fantastic to know I'll be here next season to hopefully play my part in helping the team build on what has been a really positive campaign to date.
"I've learned a massive amount from training and playing alongside quality second rows like Al Kellock, Richie Gray, Tom Ryder and Rob Verbakel, and with [current Newcastle Falcons Player of the Season] Tim Swinson also coming into the mix next season, there's sure to be great competition for places again."
Head coach Sean Lineen said: "In the games he's had in the RaboDirect PRO12, Nick has shown he has the potential to develop into a very capable player for Glasgow Warriors.
"He's always keen to learn and take advice on board, and he's also a Glasgow lad through and through. He knows what it means to pull on that black and blue shirt and that's massively important in terms of the culture we're encouraging here."
Warriors Elite Development coach Iain Monaghan said: "I'm really pleased for Nick that he will have the opportunity to continue to progress with Glasgow.
"He has come on significantly as a player in the last two seasons, and we'll continue to support and challenge him to make sure he moves forward in the same vein."
