Sky Sports News understands Cardiff have paid a fee in the region of £3.5m for the 27-year-old. Cunningham has signed a contract until 2021 at the Cardiff City Stadium.
The left-back is Cardiff's second signing of the summer after Josh Murphy's move from Norwich was completed on Tuesday.

"It's fair to say that I've been an admirer of Greg for a number of years and that he's consistently been one of the best left-sided defenders for club and country," Cardiff manager Neil Warnock told the club's website.
"We're delighted to have his experience and knowledge so as to supplement Joe Bennett who had a great time last season.
"I anticipate that Greg coming in will give us a lot of strength down that left-hand side."
Cunningham, who is a Republic of Ireland international, made 21 appearances for Preston last season.
