Tuson, 23, has agreed a two-year deal with the Wildcats and becomes coach Richard Agar’s first new recruit for the 2014 campaign.
Agar said: “I’m delighted we’ve been able to sign Chris.
“He’s quite an experienced player now and he’s been a regular in a very strong side and arguably the best side in the competition over recent seasons.
“I think Chris will help us create a very hard edge while being ruthless because he’s a very aggressive and competitive player.”
Tuson featured in Wigan’s 36-23 win over Wakefield on Sunday and admitted it was hard for him to consider a move away from the DW Stadium.
He said: “It’s been a bit of a strange one because I’ve been at Wigan all my life so I’ve never signed for another team and that’s obviously new to me.
“I spoke to Richard Mathers because I know him from when he used to play at Wigan and he said good things and they are a really good team as they proved on Sunday, it was a really tough game.
“I’m really excited and looking forward to coming here and showing Wakefield and the fans what I can do as well as bringing as my experience from playing in the Wigan team.
“I am a Wigan player and I want to see this season out with Wigan. I’ve come through this system with quite a few of the boys and I want to finish well, win some trophies and have a real strong end to 2013 then I can start thinking about Wakey.”
Tuson will officially become a Wakefield player at the end of the 2013 season and could line up against Wigan next year.
