The purpose of this paper is the study of zero-divisor graphs of a commutative multiplicative hyperrings, as a generalization of commutative rings. In this regards we consider a commutative multiplicative hyperring (𝑅,+,𝑜), where (𝑅,+) is an abelian group, (𝑅,+) is a semihypergroup and for all 𝑎,𝑏,𝑐∈𝑅, :𝑎 𝑜 (𝑏+𝑐)⊆𝑎 𝑜 𝑏+𝑎 𝑜 𝑐 and (𝑎+𝑏) 𝑜 𝑐⊆𝑎 𝑜 𝑏+𝑎 𝑜 𝑐. For 𝑎∈𝑅 a nonzero element 𝑎∈𝑅 is said to be a zero-divisor of 𝑎, if 0∈𝑎 𝑜 𝑏 and the set of zero-divisors of 𝑅 is denoted by 𝑍(𝑅). We associative to 𝑅 a zero-divisor graph 𝛤(𝑅), whose vertices of 𝛤(𝑅) are the elements of 𝑍(𝑅)∗(=Z(R)\{0}) and two distinct vertices of 𝛤(𝑅) are adjacent if they were in 𝑍(𝑅). Finally, we obtain some properties of 𝛤(𝑅) and compare some of its properties to the zero-divisor graph of a classical commutative ring and show that almost all properties of zero-divisor graphs of a commutative ring can be extend to 𝛤(𝑅) while 𝑅 is a strongly distributive multiplicative hyperring.
