A rubber composition for a studless tire according to an embodiment includes a rubber component containing a natural rubber and a polybutadiene rubber; oil-absorbent polymer particles having a glass transition temperature of −70 to −20° C., formed from a polymer whose molecular weight distribution is less than 3.0, and having an oil absorption of 100 to 1,500 ml/100 g; and an oil. The content of the oil-absorbent polymer particles is 0.5 to 25 parts by mass per 100 parts by mass of the rubber component. As a result, on-ice performance and rolling resistance performance can be improved.
