Wolves have signed defender Steven Mouyokolo from Hull City for an undisclosed fee.
The 23-year-old Frenchman has put pen to paper on a four-year contract at Molineux.
Mouyokolo, who began his career in the lower leagues in France, joined the Tigers last summer.
He made 21 Premier League appearances for the KC Stadium outfit last season as they were relegated from the top-flight.
The highlight of his campaign was a goal in a 1-1 draw with eventual champions Chelsea in February.
Mouyokolo is the third new signing made by manager Mick McCarthy since the last season ended.
Defender Jelle Van Damme and striker Steven Fletcher have also arrived at Molineux in recent weeks.
