The (Philosophical Dictionary) is an encyclopedic dictionary published by the Enlightenment thinker Voltaire in 1764. The alphabetically arranged articles often criticize the Roman Catholic Church, Judaism, Islam, and other institutions. The first edition, released in June 1764, went by the name of . It was 344 pages and consisted of 73 articles. Later versions were expanded into two volumes consisting of 120 articles. The first editions were published anonymously in Geneva by Gabriel Grasset.

What he created is a text which educated and amused at the same time. Voltaire's motivations for writing the Philosophical Dictionary can be seen as serendipitous. The idea was spawned at a dinner party in the court of Prince Frederick II of Prussia in 1752, during which he and other guests each agreed to write an article and share them the next morning. Voltaire consequently was the only guest
