Abstract: The algebra $M_n(F)$ of all $n\times n$ matrices over a field $F$ has a natural $\mathbf{Z}_n$-grading $M_n(F)=\sum _{\alpha\in \mathbf{Z}_n}\bigoplus\mathcal{M}_n^{(\alpha )}$. In this paper graded identities of the $\mathbf{Z}_n$-graded algebra $M_n(F)$ over a field of characteristic zero are studied. It is shown that all the $\mathbf{Z}_n$-graded polynomial identities of $M_n(F)$ follow from the following:

\begin{displaymath}x_1x_2-x_2x_1=0,~~~~\alpha (x_1)=\alpha (x_2)=\overline{0};\end{displaymath}

\begin{displaymath}x_1xx_2-x_2xx_1=0,~~~~\alpha (x_1)=\alpha (x_2)=-\alpha (x).\end{displaymath}
