The present invention relates to a thermoplastic resin composition and a molded article including the same. More specifically, the thermoplastic resin composition of the present invention includes 100 parts by weight of a base resin consisting of 10 to 30 % by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) including an acrylate rubber having an average particle diameter of 0.05 to 0.15 [mu]m, 20 to 40 % by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) including an acrylate rubber having an average particle diameter of 0.3 to 0.5 [mu]m, 0 to 35 % by weight of an aromatic vinyl polymer (B), and 10 to 60 % by weight of a polymethacrylate (C); and 0.5 to 10 parts by weight of a polyamide (D). According to the present invention, a low-gloss thermoplastic resin composition having mechanical properties and processability equal or superior to those of conventional ASA-based resins; having excellent weather resistance; exhibiting
