A method for producing a rubber wet masterbatch comprises a step (i) of dispersing an inorganic filler into a dispersing solvent in the presence of a cellulose fiber to produce a slurry solution, a step (ii) of mixing the slurry solution and a rubber latex solution with each other to produce a slurry-containing rubber latex solution, and a step (iii) of solidifying and drying the slurry-containing rubber latex solution to produce the rubber wet masterbatch. The cellulose fiber has an average fiber diameter less than 1000 nm. When an amount of solid in the rubber latex solution blended in the step (ii) is regarded as 100 parts by mass, a blend amount of the cellulose fiber is from 0.1 to 50 parts by mass.
