The Rainbow is a novel by British author D. H. Lawrence, first published by Methuen & Co. in 1915. It follows three generations of the Brangwen family living in Nottinghamshire, focusing particularly on the individual's struggle to growth and fulfilment within the confining strictures of English social life. Lawrence's 1920 novel Women in Love is a sequel to The Rainbow.

David Herbert Lawrence was an English novelist, short story writer, poet, playwright, literary critic, travel writer, essayist, and painter. His modernist works reflect on modernity, social alienation and industrialization, while championing sexuality, vitality and instinct. Several of his novels, Sons and Lovers, The Rainbow, Women in Love, and Lady Chatterley's Lover, were the subject of censorship trials for their radical portrayals of sexuality and use of explicit language.
