We introduce an iterative method for finding a common fixed point of a countable family of multivalued quasi-nonexpansive mapping {𝑇𝑖} in a uniformly convex Banach space. We prove that under certain control conditions, the iterative sequence generated by our method is an approximating fixed point sequence of each 𝑇𝑖. Some strong convergence theorems of the proposed method are also obtained for the following cases: all 𝑇𝑖 are continuous and one of 𝑇𝑖 is hemicompact, and the domain 𝐾 is compact.
