I am delighted to announce we have completed the appointment of Philippe Montainer as head coach #NFFC— @FAWAZ_ALHASAWI (@fawaz_alhasawi1) June 27, 2016
Forest have been searching for a new boss for some time, but they have finally managed to place someone in charge ahead of the new season.
The Reds have been without a permanent boss ever since the departure of Dougie Freedman towards the back end of last season.
Forest first went after Gus Poyet, but they were unable to convince the Uruguayan to join, and ended up having to look elsewhere.
A host of other managers were linked with the Forest job, but Montanier eventually was named.
Montanier has already managed Boulogne, Valenciennes, Real Sociedad and Rennes during his career to date.
His task at Forest looks a tough one, with the Frenchman facing a race against time to prepare for the new campaign.
Forest finished in last season in 16th place in the Championship, and will be hoping to climb up the standings next time around.
