Éditions du Seuil (edisjɔ̃ dy sœj), also known as Le Seuil, is a French publishing house established in 1935 by Catholic intellectual Jean Plaquevent (1901–1965), and currently owned by La Martinière Groupe. It owes its name to this goal "The seuil (threshold) is the whole excitement of parting and arriving. It is also the brand new threshold that we refashion at the door of the Church to allow entry to many whose foot gropes around it" (Jean Plaquevent, letter dated 28 December 1934).
Éditions du Seuil was the publisher of the Don Camillo series, and of Chairman Mao Zedong's Little Red Book. The large sales that these generated have allowed the house to publish more specialized titles, particularly in the social sciences. Seuil is widely respected in the publishing world, maintaining good relations with its authors. Seuil has published works by Jacques Lacan, Roland Barthes and Philippe Sollers (in his first period), and later by Edgar Morin, Maurice Genevoix and Pierre Bourdieu. Notably, they published Frantz Fanon's doctoral thesis, Black Skin, White Masks, in 1952, and the first edition of Aleksandr Solzhenitsyn's The Gulag Archipelago (in Russian as Архипелаг ГУЛАГ) in 1973.
Similarly, Seuil's good relations with book retailers have allowed it to establish significant distribution activity, ensuring the circulation of the works of such publishers as Odile Jacob, Éditions de Minuit, José Corti, and Rivages.
Éditions du Seuil has also performed significant activities in children's literature. The house has promoted and published many great French children's authors; in 2005 Éditions du Seuil was the first to offer to the public animated films included in their albums that were produced by the artists themselves, such as À Quai by Sara and Promenade d'un distrait, by Béatrice Alemagna.
In 1937, Éditions du Seuil was bought by Paul Flamand and Jean Bardet. In 1979 these two left the direction to Michel Chodkiewicz.
The leadership was subsequently ensured by Claude Cherki from 1989.
