Rising stars Ollie Partington, Morgan Smithies and Jack Wells have all agreed new deals with Wigan.
Front-rower Partington, 20, and loose forward Smithies, 18, have both penned four-year contracts with the Warriors while back-rower Wells, 21, has signed a two-year deal.
All three have previously played for England Academy at international level.
Warriors executive director Kris Radlinski, said: “Developing our own stars of the future is of the upmost importance to Wigan Warriors.
“We have a proud history of developing the game’s finest players, and in Oliver, Morgan and Jack we are of the firm belief that these three youngsters have a bright future at the heart of Wigan Warriors sides for years to come.
“There’s still plenty of hard-work to come for all three of these players, and we’re confident that they are in the best environment to realise their potential.
“Both Oliver and Morgan have broken into the first team and made an impact this season, which is extremely encouraging considering how young they both are.
“In Jack, we have an extremely talented player in our ranks. We have supported him through a difficult period of injuries and rewarded him for his commitment and hard-work to battle back from injury with a new deal.”
