Submission (French: Soumission) is a novel by French writer Michel Houellebecq. The French edition of the book was published on 7 January 2015 by Flammarion, with German (Unterwerfung) and Italian (Sottomissione) translations also published in January. The book instantly became a bestseller in France, Germany and Italy. The English edition of the book, translated by Lorin Stein, was published on 10 September 2015.

The novel imagines a situation in which a Muslim party upholding Islamist and patriarchal values is able to win the 2022 presidential election in France with the support of the Socialist Party. The book drew an unusual amount of attention because, by coincidence, it was released on the day of the Charlie Hebdo shooting.

The novel mixes fiction with real people: Marine Le Pen, François Hollande, François Bayrou, Manuel Valls, and Jean-François Copé, among others, fleetingly appear as characters in the book.

The novel's narrator is François, a middle-aged literature professor at Paris 3 and specialist in Huysmans. In 2022 François feels he is at the end of his sentimental and sexual life – composed largely of year-long liaisons with his students. It has been years since he did any valuable university work. France is in the grip of political crisis – in order to stave off a National Front victory, the Socialists ally with the newly formed Muslim Brotherhood Party, with additional support from the Union for a Popular Movement, formerly the main right-wing party. They propose the charming Islamic candidate Mohammed Ben-Abbes for the presidency against the National Front leader Marine Le Pen. In despair at the emerging political situation, and the inevitability of antisemitism becoming a major force in French politics, the parents of François's young and attractive Jewish girlfriend, Myriam, emigrate to Israel, taking her along with them. His mother and father die. He fears that he is heading towards suicide, and takes refuge at an abbey situated in the town of Ligugé; it is also where his literary hero, Huysmans, became a lay member.

Ben-Abbes wins the election, and becomes President of France. He pacifies the country and enacts sweeping changes to French laws, privatizing the Sorbonne, thereby making François redundant with full pension as only Muslims are now allowed to teach there. He also ends gender equality, allowing polygamy. Several of François's intellectually-inferior colleagues, having converted to Islam, get good jobs and make arranged marriages with attractive young wives. The new president campaigns to enlarge the European Union to include North Africa, the Muslim Levant and Turkey, with the aim of making it a new Roman Empire with the now-Islamicized France at its lead. In this new, different society, with the support of the powerful politician Robert Rediger, the novel ends with François poised to convert to Islam and the prospect of a second, better life, with a prestigious job, and wives chosen for him.

On 5 January 2015, French president François Hollande announced in an interview for France Inter radio that he "would read the book, because it's sparking a debate."

The author appeared in a caricature on the front page of the satirical magazine Charlie Hebdo on 7 January 2015, the day when the offices of the newspaper were attacked by masked gunmen who killed eight Charlie Hebdo employees. The title on the cover was: "Les prédictions du mage Houellebecq : en 2015, je perds mes dents, en 2022, je fais ramadan." (English: "The predictions of the sorcerer Houellebecq: In 2015, I lose my teeth. In 2022, I observe Ramadan.")

On the day of the publishing of the book and hours before the attack on Charlie Hebdo, Houellebecq said in an interview for France Inter radio:
