The present invention relates to a thermoplastic resin composition, a method of preparing the thermoplastic resin composition, and an injection molded product including the thermoplastic resin composition. More specifically, the present invention relates to the thermoplastic resin composition and the injection molded product including the same. The thermoplastic resin composition includes: a (meth)acrylic rubber-aromatic vinyl compound-vinyl cyanide compound copolymer having a graft ratio of 32 to 42% and an average particle diameter of 500 to 1,500 Å; a (meth)acrylic rubber polymer-aromatic vinyl compound-vinyl cyanide compound copolymer having a graft ratio of 32 to 45% and an average particle diameter of 2,000 to 3,000 Å; and an (alpha-alkylstyrene)-vinyl cyanide compound copolymer in specific contents, thereby obtaining excellent impact resistance, heat resistance, durability, weatherability and other properties, and improving deposition properties, glossiness, adhesion and other properties during the non-painting process such that the thermoplastic resin composition is capable of providing an injection molded product having excellent quality.
