(57) Provided are a cement clinker and a cement composition which can be reduced in heat of hydration and are excellent in short term strength development. A cement clinker in which the proportion of C3S determined by Bogue calculation is 50-75 % by mass, the proportion of C2S determined by Bogue calculation is 5-25 % by mass, and the total proportion of C3A and C4AF determined by Bogue calculation is 15-22 % by mass, and which contains MgO, TiO2, MnO and ZnO, and satisfies the following formula (1). (1): CMg-C3A x CTi-C3A x CMn-C3A x CZn-C3A ≤ 0.0010 (in the formula (1), CMg-C3A represents the MgO content (% by mass) in C3A, CTi-C3A represents the TiO2 content (% by mass) in C3A, CMn-C3A represents the MnO content (% by mass) in C3A, and CZn-C3A represents the ZnO content (% by mass) in C3A).
