Encyclopédie, ou dictionnaire raisonné des sciences, des arts et des métiers (Encyclopedia, or a Systematic Dictionary of the Sciences, Arts, and Crafts) was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, and translations. It had many writers, known as the Encyclopédistes. It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert.

The Encyclopédie is most famous for representing the thought of the Enlightenment. According to Denis Diderot in the article "Encyclopédie", the Encyclopédie's aim was "to change the way people think" and for people to be able to inform themselves and to know things. He and the other contributors advocated for the secularization of learning away from the Jesuits. Diderot wanted to incorporate all of the world's knowledge into the Encyclopédie and hoped that the text could disseminate all this information to the public and future generations. It was also the first encyclopedia to include contributions from many named contributors, and it was the first general encyclopedia to describe the mechanical arts.

The Encyclopédie was originally conceived as a French translation of Ephraim Chambers's Cyclopaedia (1728). Ephraim Chambers had first published his Cyclopaedia, or an Universal Dictionary of Arts and Sciences in two volumes in London in 1728, following several dictionaries of arts and sciences that had emerged in Europe since the late 17th century. This work became quite renowned, and four editions were published between 1738 and 1742. An Italian translation appeared between 1747 and 1754. In France a member of the banking family Lambert had started translating Chambers into French, but in 1745 the expatriate Englishman John Mills and German Gottfried Sellius were the first to actually prepare a French edition of Ephraim Chambers's Cyclopaedia for publication, which they entitled Encyclopédie.
