In this paper, we approximate a fuzzy almost cubic function by a cubic function in a fuzzy sense. Indeed, we investigate solutions of the following cubic functional equation 3f (kx + y) + 3f (kx − y) − kf (x + 2y) − 2kf (x − y) − 3k(2k 2 − 1)f (x) + 6kf (y) = 0. and prove the generalized Hyers-Ulam stability for it in fuzzy Ba-nach spaces.
