The 24-year-old has signed a three-year contract with the Latics.
“Everyone knows how well Wilson and Maynor have done in the Premier League and it is no wonder there was lots of interest in Hendry, who comes from the same club as those two and has impressed,” Wigan boss Roberto Martinez told the club’s official website.
“What happened last season here was a shame, but the player now has the chance to prove himself over here. He is a powerful figure in midfield, who can sit in front of the back four and destroy attacks, or can also come forward and score.
“He is a player the club has worked really hard to secure these past months, with representatives from here travelling over to Honduras to meet with him and broker the deal – and all that hard work has paid off now.”
