The invention belongs to the field of petrochemical additives, and particularly relates to a natural gas organic sulfur removal agent and a preparation method thereof. The natural gas organic sulfur removal agent is prepared from a composite amine solution, a desulfurizing enhancer, a defoaming agent, an antioxidant and a preservative. The preparation method for the natural gas organic sulfur removal agent comprises the following steps that (1) steric hindered amine, methyldiethanolamine and water are uniformly mixed according to the proportion so as to prepare the composite amine solution; (2) ammonium chloride is added into ethanolamine according to the proportion, and stirring is carried out for 0.5-2 hours at 40-60 DEG C so as to obtain the desulfurization enhancer; (3) the desulfurization enhancer, the defoaming agent, the antioxidant and the preservative are added into the composite amine solution according to the proportion; and (4) stirring is carried out at the room temperature for 2-6 hours so as to
