The Carrow Road side have landed the 29-year-old forward on a temporary deal with the option to buy from Dynamo Kiev.
The 29-year-old joins on a season-long loan deal from Dynamo Kiev, with the newly promoted outfit having the option to buy the striker next summer if he is a hit at Carrow Road.
Mbokani arrives at the club with an impressive track record, having stepped out for top European clubs such as Standard Liege, Monaco, Anderlecht and Wolfsburg in the past.
In 2013 the African forward was handed the Belgian top flight’s Golden Shoe award for the best player in the division, winning the accolade ahead of bumper Manchester City signing Kevin De Bruyne, who was playing for Genk at the the time.
Since moving to the Ukrainian club in 2013, the Zaire-born star has netted 16 goals in 33 league games and boasts a comprehensive strike rate wherever he has been.
Norwich fans will hope that Mbokani can be more of a success than Ricky van Wolfswinkel, who has agreed a deal to join Spaniards Real Betis on loan.
Canaries manager Alex Neil was excited to welcome the new centre forward to the club.
"Dieumerci is going to give us competition at the top end of the pitch, and I think we've needed a bit of strengthening there,” he told the club’s official website.
"He's a big, strong number nine - he can take the ball in, he's mobile and he's a real threat in the box. We're hoping all of those things come together for him.
"He's got a good track record and he's played Champions League football, so I think it's an exciting signing for us."
