The present invention relates to a polyester resin composition and a molded article including the same. The polyester resin composition comprises: a base resin (A) consisting of a first alicyclic polyester resin (A1) and a second alicyclic polyester resin (A2); and a reactive oligomer (B). The first alicyclic polyester resin (A1) contains less than 3 mole% of a unit which is derived from isophthalic acid with respect to units derived from dicarboxylic acid components, whereas the second alicyclic polyester resin (A2) contains 3-10 mole% of unit derived from isophthalic acid with respect to the units derived from dicarboxylic acid components. 본 발명은 폴리에스테르 수지 조성물 및 이를 포함하는 성형품에 관한 것으로, 본 발명의 폴리에스테르 수지 조성물은, (A) (A1) 제1지환족 폴리에스테르 수지 및 (A2) 제2지환족 폴리에스테르 수지를 포함하는 기초 수지; 및 (B) 반응성 올리고머를 포함하며, 상기 (A1) 제1 지환족 폴리에스테르 수지는 디카르복실산 성분으로부터 유도된 단위 중 이소프탈산으로부터 유도된 단위의 비율이 3몰% 미만이고, 상기 (A2) 제2 지환족 폴리에스테르 수지는 디카르복실산 성분으로부터 유도된 단위 중 이소프탈산으로부터 유도된 단위의 비율이 3 내지 10몰%이다.
