Delusion and Dream in Jensen's Gradiva is an essay written in 1907 by Sigmund Freud that subjects the novel Gradiva by Wilhelm Jensen, and especially its protagonist, to psychoanalysis.

Gradiva is a novel by Wilhelm Jensen, first published in instalments from June 1 to July 20, 1902 in the Viennese newspaper "Neue Freie Presse". It was inspired by a Roman bas-relief of the same name and became the basis for Sigmund Freud's famous 1907 study Delusion and Dream in Jensen's Gradiva. Freud owned a copy of this bas-relief, which he had joyfully beheld in the Vatican Museums in 1907; it can be found on the wall of his study in 20 Maresfield Gardens, London – now the Freud Museum.
