An embodiment of the invention provides a coated cutting tool having a base material and a hard coating, in which: the hard coating is formed from a nitride or a carbonitride having an Al content of from 50 at. % to 68 at. %, a Cr content of from 20 at. % to 46 at. %, and an Si content of from 4 at. % to 15 at. %, relative to the total amount of metal (including semimetal) elements, and when the total of metal (including semimetal) elements, nitrogen, oxygen, and carbon is designated as 100 at. %, the atomic percentage (at. %) A of metal (including semimetal) elements and the atomic percentage (at. %) B of nitrogen satisfy the relationship 1.03≤B/A≤1.07; and, in an intensity profile obtained from an X-ray diffraction pattern or a selected area diffraction pattern of a transmission electron microscope, an intensity of a peak from the (200) plane or the (111) plane of a face-centered cubic lattice structure exhibits the maximum intensity.
