A snowball is a spherical object made from snow, usually created by scooping snow with the hands and pressing the snow together to compact it into a ball. Snowballs are often used in games such as snowball fights.

A snowball fight is a physical game in which balls of snow are thrown with the intention of hitting somebody else. The game is similar to dodgeball in its major factors, though typically less organized. This activity is primarily played during winter when there is sufficient snowfall.
