Dodsworth is a satirical novel by American writer Sinclair Lewis, first published by Harcourt Brace & Company on March 14, 1929. Its subject, the differences between US and European intellect, manners, and morals, is one that frequently appears in the works of Henry James. In 1936 it was made into a movie, Dodsworth, which received seven Academy Award nominations and has been regarded as historically significant by the Library of Congress.

Harry Sinclair Lewis was an American novelist, short-story writer, and playwright. In 1930, he became the first author from the United States to receive the Nobel Prize in Literature, which was awarded "for his vigorous and graphic art of description and his ability to create, with wit and humor, new types of characters." Lewis wrote six popular novels: Main Street (1920), Babbitt (1922), Arrowsmith (1925), Elmer Gantry (1927), Dodsworth (1929), and It Can't Happen Here (1935).
