Political fiction employs narrative to comment on political events, systems and theories. Works of political fiction, such as political novels, often "directly criticize an existing society or present an alternative, even fantastic, reality". The political novel overlaps with the social novel, proletarian novel, and social science fiction.

The social novel, also known as the social problem novel, is a "work of fiction in which a prevailing social problem, such as gender, race, or class prejudice, is dramatized through its effect on the characters of a novel". More specific examples of social problems that are addressed in such works include poverty, conditions in factories and mines, the plight of child labor, violence against women, rising criminality, and epidemics because of over-crowding and poor sanitation in cities.
