Là-Bas, translated as Down There or The Damned, is a novel by the French writer Joris-Karl Huysmans, first published in 1891. It is Huysmans's most famous work after À rebours. Là-Bas deals with the subject of Satanism in contemporary France, and the novel stirred a certain amount of controversy on its first appearance. It is the first of Huysmans's books to feature the character Durtal, a thinly disguised portrait of the author himself, who would go on to be the protagonist of all of Huysmans's subsequent novels: En route, La cathédrale and L'oblat.

Charles-Marie-Georges Huysmans was a French novelist and art critic who published his works as Joris-Karl Huysmans. He is most famous for the novel À rebours. He supported himself by way of a 30-year career in the French civil service.
