  We study the problem of distinguishing maximally entangled quantum states by
using local operations and classical communication (LOCC). A question of
fundamental interest is whether any three maximally entangled states in
$\mathbb{C}^d\otimes\mathbb{C}^d (d\geq 4)$ are distinguishable by LOCC. In
this paper, we restrict ourselves to consider the generalized Bell states. And
we prove that any three generalized Bell states in
$\mathbb{C}^d\otimes\mathbb{C}^d (d\geq 4)$ are locally distinguishable.
