An object of the present invention is to provide a golf ball resin composition that comprises an ionomer resin with an excellent resilience and fluidity. Another object of the present invention is to provide a golf ball excellent in the resilience without lowering the durability significantly in a golf ball using the ionomer resin for the intermediate layer. The present invention provides a golf ball resin composition comprising, 100 parts by mass of (A) an ionomer resin consisting of a metal ion-neutralized product of a ternary copolymer composed of ethylene, α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and α,β-unsaturated carboxylic acid ester, and from 25 parts to 100 parts by mass of (B) a metal salt of a fatty acid having 18 to 30 carbon atoms. The golf ball of the present invention is not limited, as long as it comprises a constituent member formed from the golf ball resin composition of the present invention.
