A vinyl chloride resin composition with which an increase in surface gloss can be suppressed even in the case of repeating the molding of a vinyl chloride resin molded product using the same mold and also favorable tensile elongation and low surface stickiness can be ensured is provided. A vinyl chloride resin composition comprises: a vinyl chloride resin; a plasticizer; and a silicone oil, wherein a content of the plasticizer relative to 100 parts by mass of the vinyl chloride resin is 80 parts by mass or more, a content of the silicone oil relative to 100 parts by mass of the plasticizer is 0.01 parts by mass or more, and a predetermined weight reduction rate of the silicone oil is 7.0 mass% or less.
