The invention belongs to the technical field of polyethylene fibers, and particularly relates to an ultra-fine modified magnesium hydroxide ultra-high molecular weight polyethylene fiber and a preparation method thereof. The ultra-fine modified magnesium hydroxide ultra-high molecular weight polyethylene fiber is prepared from an ultra-high molecular weight polyethylene solution and an ultra-finemodified magnesium hydroxide aqueous solution, wherein the weight ratio of the ultra-high molecular weight polyethylene solution to the ultra-fine modified magnesium hydroxide aqueous solution is 7: (3-4), the ultra-fine modified magnesium hydroxide aqueous solution comprises magnesium chloride, sodium hydroxide, a surface modifier and methyl methacrylate, and the weight ratio of the magnesium chloride to the sodium hydroxide to the surface modifier to the methyl methacrylate is (5-15): (5-15): (10-20): (5-8). The LOI value of the ultra-fine modified magnesium hydroxide ultra-high molecular weight polyethylene fiber c
