Studies on Hysteria (German: Studien über Hysterie) is an 1895 book by Sigmund Freud, the founder of psychoanalysis, and the physician Josef Breuer.

(real name: Bertha Pappenheim), seminal for the development of psychoanalysis, and four more by Freud—[1] including his evaluation of Emmy von N—[2] and finishing with a theoretical essay by Breuer and a more practice-oriented one on therapy by Freud.

[3] Freud sees symptomology as stratified in an almost geological way, with the outermost strata being easily remembered and accepted, while “the deeper one goes the more difficult it is to recognize the recollections that are surfacing”.

[6] Freud however would come to lay more stress on the causative role of sexuality in producing hysteria, as well as gradually repudiating Breuer's use of hypnosis as a means of treatment.

[15] The philosopher Mikkel Borch-Jacobsen and the psychologist Sonu Shamdasani comment that Studies on Hysteria gave Freud, "a certain local and international notoriety".
