Provided are a rubber composition for studless winter tires that can improve not only performance on snow and ice but also abrasion resistance, thereby simultaneously achieving excellent performance on snow and ice and excellent abrasion resistance, and a studless winter tire formed from the rubber composition. The rubber composition for studless winter tires contains: a rubber component; a chemically modified microfibrillated cellulose; carbon black; and silica, the chemically modified microfibrillated cellulose having an average fiber diameter of 0.1 μm or less, the rubber component having a combined amount of natural rubber and polybutadiene rubber of 30-100% by mass based on 100% by mass of the rubber component, the rubber composition containing, per 100 parts by mass of the rubber component, 1-10 parts by mass of the chemically modified microfibrillated cellulose, 10-80 parts by mass of the carbon black, and 10-80 parts by mass of the silica.
