The present disclosure relates to a composite resin composition for automotive interior materials and an automotive interior material using the same. The composite resin composition includes a polyester-based resin satisfying a specific intrinsic viscosity range and a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound copolymer and an aromatic vinyl compound-vinyl cyanide compound copolymer satisfying specific melt index ranges. The automotive interior material manufactured using the composite resin composition has advantages in that the automotive interior material is used as an unpainted product while cost is reduced due to material improvement, whereby it is possible to achieve high economic efficiency. In addition, the automotive interior material satisfies required physical properties, such as chemical resistance and mechanical strength, and at the same time exhibits high formability and noise resistance, whereby external appearance quality and emotional quality are improved.
