The invention discloses a multi-principal-element alloy material coating and a preparation method thereof, and belongs to the fields of metal materials and metal material preparation. The chemical formula of the multi-principal-element alloy material coating is AlxCoCuFeyMnzNiRep, and Re is the rare earth element Ce or Y. The preparation method comprises the specific steps that metal powder and rare earth oxide are weighed according to the chemical formula and placed into a ball milling tank, an appropriate number of stainless steel balls are added, and the ball milling tank is sealed under inert gas; the sealed ball milling tank is put on a planetary ball mill for material mixing; organic glue is added into the uniformly-mixed powder to be blended into a pasty mixture, and the mixture is prefabricated on a base body to be dried; and plasma cladding is conducted on the base body material with the prefabricated raw material, and then the multi-principal-element alloy coating is obtained. According to the multi
