A tire masterbatch comprises natural rubber and cellulose nanofiber, wherein at least a portion of the cellulose nanofiber is such that length is 10 μm to 20 μm, and a ratio (i.e., L/D) of the length to a diameter is 1000 to 2000. A tire masterbatch manufacturing method comprises an operation in which at least a cellulose nanofiber slurry and a natural rubber latex are mixed to prepare a liquid mixture, and an operation in which the liquid mixture is coagulated, wherein at least a portion of cellulose nanofiber within the cellulose nanofiber slurry is such that length is 10 μm to 20 μm, and a ratio (i.e., L/D) of the length to a diameter is 1000 to 2000.
