North and South is a social novel published in 1854–55 by English author Elizabeth Gaskell. With Wives and Daughters (1865) and Cranford (1853), it is one of her best-known novels and was adapted for television three times. At first, Gaskell wanted the novel to be titled after the heroine, Margaret Hale, but Charles Dickens, the editor of Household Words, the magazine in which the novel was serialised, insisted on North and South.

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.
