The present invention relates to a hot-rolled galvanizing steel sheet having excellent galling resistance and formability, and a method for manufacturing the same. According to an embodiment of the present invention, provided is a hot-rolled galvanizing steel sheet, comprising: a base steel; and a hot-rolled galvanizing layer formed on the surface of the base steel, wherein the hot-rolled galvanizing layer provides a hot-rolled galvanizing steel sheet having a Mn crystallite having a size of 10 µm or less between the resin dendrites of zinc that form sequins, and in addition, provided is a method for manufacturing a hot-rolled galvanizing steel sheet comprising: depositing a steel sheet to be plated in a hot-rolled galvanizing solution at a temperature of 440 ° C to 480 ° C containing 0.05 to 0.6 wt% of manganese, 99 wt% or more of zinc and unavoidable impurities, applying the plating solution to the same and taking out the same therefrom; then cooling the steel sheet applied with the hot-rolled galvanizing solution to solidify the plating solution and form a plating layer, wherein the cooling is performed at a cooling rate of -10° C/s or lower in a section where a steel sheet has a temperature of 430° C to 410° C.
