A thermoplastic resin composition and a molded article formed of the same. The thermoplastic resin composition includes: about 100 parts by weight of a polycarbonate resin; about 5 to about 20 parts by weight of a rubber modified aromatic vinyl copolymer resin; about 0.5 to about 3 parts by weight of a maleic anhydride-grafted rubber polymer; about 50 to about 100 parts by weight of glass fibers; about 10 to about 30 parts by weight of barium sulfate; and about 5 to about 20 parts by weight of a phosphorus flame retardant. The thermoplastic resin composition can have high specific gravity and good properties in terms of impact resistance, weather resistance, flame retardancy, fluidity, and the like.
