摘要： A dielectric ceramic composition and a multilayer ceramic capacitor including the same are provided. The dielectric ceramic composition includes a BaTiO3-based base material main ingredient and an accessory ingredient, where the accessory ingredient includes dysprosium (Dy) and niobium (Nb) as first accessory ingredients. A total content of the Dy and Nb is less than or equal to 1.5 mol, based on 100 mol of Ti of the base material main ingredient, and a content of the Dy satisfies 0.7 mol
