This Zn-plated hot stamped product includes a steel, a Zn-based plating layer, and an oxide layer, in which an upper layer which is a region on a surface side of the Zn-based plating layer has a two-phase structure of a Γ phase and an Fe—Zn solid solution, and a lower layer which is a region of the Zn-based plating layer excluding the upper layer has a single-phase structure of an Fe—Zn solid solution, an upper layer thickness and a lower layer thickness satisfy the following expression, a Mn content ratio of Max. Mn/Min. Mn, which is a ratio of a maximum value Max. Mn to a minimum value Min. Mn of an Mn content on a surface of the Zn-plated hot stamped product, is 10.0 or less, and an average value Ave. Mn is 0.5 to 7.5% by mass %. 0.20≤upper layer thickness/(upper layer thickness+lower layer thickness)≤0.80
