Abstract: Provided are: a stabilizer composition capable of imparting a vinyl chloride resin with excellent thermal stability, coloration resistance, and thermal coloration resistance; a vinyl chloride resin composition containing the same and a molded article of the composition. The stabilizer composition contains, with respect to 100 parts by mass of a component (A): 5 to 700 parts by mass of a component (B) and 5 to 200 parts by mass of a component (C). The component (A) is at least one organic acid zinc salt, the component (B) is at least one selected from the group consisting of organic acid barium salts, overbased barium carbonates, organic acid calcium salts and overbased calcium carbonates, and the component (C) is at least one hindered amine-based light stabilizer.
