A resin composition for a golf ball excellent in resilience and flexibility, and a golf ball excellent in resilience and feel at impact are provided. (A) (a-1) A binary copolymer of an olefin and an α, β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-2) an olefin and 3 to 8 carbon atoms (A-3) Olefin, C3-C8 α, β-unsaturated carboxylic acid and α, β- A ternary copolymer with an unsaturated carboxylic acid ester, and (a-4) an olefin, an α, β-unsaturated carboxylic acid with 3 to 8 carbon atoms and an α, β-unsaturated carboxylic acid ester. For golf balls containing at least one selected from the group consisting of neutralized metal ions of an original copolymer, and (B) a compound having a hydrocarbon chain, a cationic moiety and an anionic moiety in the molecule The present invention relates to a resin composition.
