Let [Formula: see text] be the ring of integers modulo [Formula: see text] where [Formula: see text] is a prime and [Formula: see text] is a positive integer, [Formula: see text] the [Formula: see text] matrix ring over [Formula: see text]. The zero-divisor graph of [Formula: see text], written as [Formula: see text], is a directed graph whose vertices are nonzero zero-divisors of [Formula: see text], and there is a directed edge from a vertex [Formula: see text] to a vertex [Formula: see text] if and only if [Formula: see text]. In this paper, we completely determine the automorphisms of [Formula: see text].
