The Outsiders is a coming-of-age novel by S.E. Hinton published in 1967 by Viking Press. The book details the conflict between two rival gangs of White Americans divided by their socioeconomic status: the working-class "Greasers" and the upper-middle-class "Socs". The story is told in first-person perspective by teenage protagonist Ponyboy Curtis, and takes place in Tulsa, Oklahoma in 1965, although this is never explicitly stated in the book.

Greasers are a youth subculture that emerged in the 1950s and early 1960s from predominantly working class and lower-class teenagers and young adults in the United States and Canada. The subculture remained prominent into the mid-1960s and was particularly embraced by certain ethnic groups in urban areas, particularly Italian Americans, Hispanic Americans, and Latin Americans.
