The midfielder helped Wolves to stay in the Premier League last season but left after not agreeing a new contract with the club and spent the summer on trial with the Latics, earning himself a full-time deal.
He told Wigan's official website: "I've been an admirer of the club's style of play ever since Roberto took charge and that kind of play is what I'm all about.
"It was nice to get 45 minutes under my belt against Preston at the weekend and get a run out with my new team mates. On the basis of that appearance I'm confident I can adjust to the team's game plan quite easily.
"On a personal level I think this is a club where I can improve as a footballer and hopefully with that help the team progress at the same time.
"Hopefully I can get some more minutes under my belt when we face Villarreal this weekend and put in a performance that gives the manager plenty to think about when the season kicks off."
Jones maintained that it was tough to leave Wolves but could not be happier to have signed for Wigan.
"I'm delighted to have joined Wigan Athletic. I've been training at the club for a little while now and to have been offered a permanent deal is fantastic," he said.
"Originally I came to the club in order to get myself fit which the manager and staff allowed me to do and thankfully that led to me earning a deal. Now I'll be heading into training as a Wigan Athletic player which is a great feeling.
"I had three successful years at Wolves, gaining promotion and then securing the club in the Premier League, so it was a tough decision to leave Molineux where I've a lot of fond memories, but now I'm hoping to continue with my career and continue improving here at Wigan Athletic."
Jones came through the Manchester United youth academy but could not break into the first team at Old Trafford.
