The invention belongs to the field of chemical engineering and relates to a titanium dioxide pigment and a preparation method thereof. The titanium dioxide pigment is prepared by putting a titanium dioxide base material prepared by using a process into a coating tank, and by coating the titanium dioxide base material by a coating agent, wherein the coating agent is Al2O3, SiO2 or ZeO2. The titanium dioxide pigment provided by the invention is high in glossiness and good in dispersability in an ink or similar system, and is relatively simple in preparation procedure.
