The invention discloses a multi-principal element alloy for powder metallurgy high performance cutting tools and a preparation method of the multi-principal element alloy, and belongs to the field ofmetal materials and preparation thereof. The chemical formula of the multi-principal element alloy is AlCoCuMnNiMZn, wherein x is greater than or equal to 0.1 and less than or equal to 1.3, yis greater than or equal to 0.1 and less than or equal to 0.4, and z is greater than or equal to 0.1 and less than or equal to 1.3; x/(x+y+z+4) is greater than 0.01 and less than 0.25, y/(x+y+z+4) isgreater than 0.01 and less than 0.10, and z/(x+y+z+4) is greater than 0.01 and less than 0.25; and M is a rare earth element Ce or Y. The composition of the multi-principal element alloy material prepared by the method is consistent with the composition of the raw material ratio, the structure of the alloy formed is simple, and the formation of an intermetallic compound is effectively inhibited;and the preparation method for the mu
