Provided are a cathode active material for a secondary battery, a method of manufacturing the same, and a cathode for a secondary battery including the cathode active material. Specifically, the present invention relates to a cathode active material including a lithium-containing transition metal oxide and two or more metal composite oxide layers selected from the group consisting of Chemical Formulae 1 to 3 which are coated on the surface of the lithium-containing transition metal oxide, a method of manufacturing the same, and a cathode for a secondary battery including the cathode active material,
