Hill, 25, joined the Wolves from Leigh ahead of the 2012 season, and is now committed until November 2018.
He said: “It’s a great club to be a part of, up there fighting for trophies. It’s a great all-round club to be involved in.
“I’m glad to have secured my deal and to be playing for the Wolves for the next five years. It’s down to the players I’ve played with and a great coach.
“The disappointment of how the last two years ended means we will be fighting once again next year to make it one step further in both competitions.”
Coach Tony Smith said: “We are delighted that Chris has committed himself to the club for the next five years. He has been a recent success story in making the transition from the Championship into the Super League and now with England on the International scene.
“We look to maintain a stable squad each year to keep building and striving to get better and better; Chris is one of a number of players who we have secured on a long-term deal and we are proud to be a club to which players are keen to commit.
“We once again look forward to seeing Chris making an impact in the side for the foreseeable future.”
