De Ridder had his contract cancelled by Blues on Monday and has now signed a three-year deal with Wigan.
The Dutchman made just 12 first-team appearances for the club and is now looking forward to playing under Bruce again at the JJB Stadium.
"When a manager says he wants you for his team, it is very flattering, especially when it is a big team like Wigan who are now well established in the Premier League," De Ridder told the club's official website.
The former Holland Under 21 international is Wigan's first signing of the summer, but Bruce is hoping De Ridder will not be the last arrival.
Bruce said: "Daniel is an exciting player and I'm convinced he can make an impact at Wigan.
"He has very quick feet and can pull off the unexpected, he's a player with a trick, who can go past defenders and has an eye for a pass.
"He is also versatile enough to play in a number of positions."
