In Naruto Shippuuden is Naruto an Akatsuki?

No! Naruto will never join the akatsuki!

Another answer:

Even if naruto want to join Akatsuki he can't because the main gold of the Akatsuki is to capture all 9 tailed beast .that is to complete Madara(ToBi) plan of the moon eye . therefore they're no chance in hell naruto can join Akatsuki

yes naruto does not join he is with the leaf till he becomes hokaga then dies but BUT BUT it would make sense for him to join the akatsuki because if they want him for madara a.k.a obito a.k.a Tobi moon eye thing they will just use him like sasoris stupid puppets oh and if you are woundering sasori is the first to die in the akatsuki
