A nanocomposite and thermoplastic nanocomposite resin composition using the same are disclosed. The nanocomposite comprises about 100 parts by weight of a rubber- modified graft copolymer and about 0.1-50 parts by weight of colloidal metal or metal oxide nanoparticles. The colloidal metal or metal oxide nanoparticles are bound to the surface of the rubber-modified graft copolymer. The thermoplastic nanocomposite resin composition comprises about 10-40 parts by weight of the nanocomposite and about 60-90 parts by weight of a thermoplastic resin. The thermoplastic nanocomposite resin composition has good mechanical properties such as impact strength, tensile strength, and modulus.
