Zusammenfassung:	The invention relates to the technical field of metallurgy and provides a thin-walled TC4 titanium alloy seamless tube and a production method thereof. The method includes the steps that a round billet is heated, wherein the titanium alloy round billet is heated to 950-960 DEG C; perforating is performed, wherein perforating is performed on the heated round billet, and a pierced billet is formed; finishing is performed, wherein the outer surface of the pierced billet is ground, and sand blasting is performed on the inner surface of the pierced billet; pushing is performed, medium-frequency pushing is performed on a titanium alloy tube at the temperature of 860-890 DEG C, and the deformation amount is made to be larger than 25%; acid pickling is performed; cold rolling is performed, wherein the titanium alloy tube where acid pickling is performed is subjected to cold rolling through a cold rolling machine, and the wall of the titanium alloy tube is reduced by 2 mm; and the pushing procedure, the acid pickling
