A coated cutting tool comprising a substrate and a coating layer formed on a surface of the substrate, wherein: the coating layer comprises a lower layer including at least one Ti compound layer containing a specific Ti compound, an intermediate layer including an α-type Al2O3 layer containing α-type Al2O3, and an upper layer including a TiCN layer containing TiCN; the respective layers are laminated in this order from the substrate side toward a surface side of the coating layer; an average thickness of the coating layer is from 5.0 μm or more to 30.0 μm or less; and an angle formed by a normal to a cross-sectional surface which is located within a predetermined range below a surface of the intermediate layer and is parallel to the surface of the substrate and a normal to a (001) plane of a particle of an α-type Al2O3 layer, and an angle formed by a normal to a cross-sectional surface which is located within a predetermined range below a surface of the upper layer and is parallel to the surface of the substrate and a normal to a (111) plane of a particle of a TiCN layer, respectively satisfy predetermined conditions.
