Édouard Pichon (24 June 1890 – 20 January 1940) was a French pediatrician, grammarian and psychoanalyst.

A distinguished and innovative grammarian,[1] Pichon was analysed by Eugénie Sokolnicka, and became a founding member of the Paris Psychoanalytic Society in 1926.

[4] Through his mixture of linguistic and psychoanalytic thinking, Pichon was a powerful influence on Jacques Lacan (as well as a practical mentor).

[5] In Écrits, Lacan paid tribute to "a divination that I can attribute only to his practise of semantics...that guided him in people's dark places".

[6] Among the psychoanalytic concepts introduced by what Élisabeth Roudinesco called Pichon's "fatalist genius",[7] were those of oblatory, scotomization, and foreclosure.
