PROBLEM TO BE SOLVED: To provide a crystal nucleating agent composition effective in providing sufficient transparency and a crystalline polymer composition containing the crystal nucleating agent composition. SOLUTION: The crystal nucleating agent composition comprises 100 pts. mass of a crystal nucleating compound represented by general formula (I), 5-50 pts. mass of an aliphatic organic acid lithium represented by general formula (II), and 5-50 pts. mass of an aliphatic organic acid metal salt represented by general formula (III), wherein R<SP>1</SP>and R<SP>2</SP>each denotes a 1-4C alkyl group; R<SP>3</SP>denotes a hydrogen atom or a 1-4C alkyl group; R<SP>4</SP>and R<SP>5</SP>each denotes a group to be introduced from a 10-30C aliphatic organic acid; and M denotes a bivalent metal atom.
