Warrington have handed new deals to Tom Lineham, Toby King and Joe Philbin until the end of 2021.
Lineham, 26, joined the Wolves from Hull and has scored 63 tries in 88 appearances since his debut in 2016.
Centre King and Warrington-born prop Philbin both came through the club’s academy, with Philbin just three short of a century of appearances.
All three were last week named in the England Knights squad.
Coach Steve Price said: “It’s exciting for all three to put pen to paper. They are all young players who love being around this squad. We’ve got a fantastic playing group here and we want to secure that core squad for years to come. It’s about developing an environment and culture that players want to be a part of.
“Joe (Philbin) is a local lad and I love everything he stands for, he’s a quality person as well as player who has a big impact up front for us, and there’s still much more to come from Joe. He is great to have within the squad and is always full of beans; all the lads love playing alongside him.
“Toby (King) is a quality player who is happy to adapt to any position that will best help the team. He is a team-first player which is what we encourage at this club. He has developed as a player and is now starting to cement his place within the team. His recent England Knights selection is just the first step on his road to higher honours.
“I thought Tom (Lineham) finished off the season really well last year. He’s a great player to have around the club and he’s certainly a character adding a positive vibe to the squad. There’s so much more football in Tom and we look forward to seeing that emerge over the years to come.”
