The 25-year-old has put pen to paper on a three year contract at the KCOM Stadium.
Dicko, who had previously had a short spell on loan at Molineux at the end of the 2012/13 season, joined Wolves on a permanent basis in January, 2014.
He made an impressive return to Wolves after joining permanently, scoring 13 goals in that second half of the season as the team stormed to the Sky Bet League One title.
Dicko also stayed among the goals in the 2014/15 campaign, notching 15 as Wolves missed out on the Championship play-offs on goal difference despite amassing an impressive haul of 78 points.
That tally was enough to see him finish as joint top scorer alongside Bakary Sako.
Unfortunately Dicko was to suffer a serious cruciate knee ligament injury in the first month of the following season, which was to rule him out for over a year.
Back fit now for the last year, his career record at Wolves including the loan spell is 108 appearances in all competitions – 100 in the league - scoring 35 goals.
Everyone at Wolves would like to thank Nouha for his fantastic efforts for the club and wish him all the very best for the future.
