Roger Bastide (Nîmes, 1 April 1898 – Maisons-Laffitte, 10 April 1974) was a French sociologist and anthropologist, specialist in sociology and Brazilian literature.
Bastide is known for his contributions to the study of Afro-Brazilian and Afro-Caribbean religions. Bastide's "The African Religions of Brazil: Toward a Sociology of the Interpenetration of Civilizations" (1960) documented Afro-Brazilian religions such as Catimbo, Xango, Candomblé, Macumba, Umbanda, and Batuques. Bastide also published "Le Candomblé de Bahia" (1958) and "African Civilizations in the New World", translated in 1971.
The character Agliè in Umberto Eco's Foucault's Pendulum bears resemblance to Roger Bastide.
