Table of Contents:

Let $(Γ,+)$ be an Abelian group of order $n^2$ and MS$_Γ(n)$ be an $n\times n$ array whose entries are all elements of $Γ$. Then MS$_Γ(n)$ is a $Γ$-magic square if all row, column, main and backward main diagonal sums are equal to the same element $μ\inΓ$. We prove that for every Abelian group $Γ$ of order $n^2$, $n>2$, there exists a magic square MS$_Γ(n)$ where the square entries are elements of $Γ$.
