  The fine curve graph of a surface was introduced by Bowden, Hensel, and Webb
as a graph consisting of essential simple closed curves on the surface. Long,
Margalit, Pham, Verberne, and Yao proved that the automorphism group of the
fine curve graph of a closed orientable surface is isomorphic to the
homeomorphism group of the surface. In this paper, based on their argument, we
prove that the automorphism group of the fine curve graph of a closed
nonorientable surface $N$ of genus $g \geq 4$ is isomorphic to the
homeomorphism group of $N$.
