[PROBLEMS] To impart excellent coloration resistance to a vinyl chloride resin without reducing thermal stability with a small addition amount without using heavy metals such as lead, cadmium, tin, and barium. Provided is a stabilizer composition for vinyl chloride resin. A stabilizer composition for a vinyl chloride resin containing (A) an organic acid calcium salt and / or an organic acid zinc salt, (B) a β-diketone compound, and (C) a blue pigment, The mass ratio of the component (A) to the component (B) ((A) :( B)) is in the range of 99.9: 0.1 to 15.0: 85.0, and the component (C) Is 0.1 to 5.0 parts by mass with respect to 100 parts by mass in total of the component (A) and the component (B), and a stabilizer composition for vinyl chloride resin.
