Snowball is a fictional pig in the book Animal Farm written by George Orwell. Together with the pig Napoleon, he leads the animals' revolt against the human farmer, but is driven away from the farm (a comparison to the Russian government) by his former comrade Napoleon in the later part of the story. Unlike Napoleon, he has the best interests of the animals in mind.
