Suzuki [Discrete Math.310(2010), 6–11] proved that for any orientable closed surfaceF2other than the sphere, there exists an optimal 1‐planar graph which can be embedded onF2as a triangulation. However, for nonorientable closed surfaces, the existence of such graphs is unknown. In this article, we prove that no optimal 1‐planar graph triangulates a nonorientable closed surface.
