Les Mythes du Temple Solaire

Les Mythes du Temple Solaire is a book by religious historian Jean-François Mayer. It was published in 1996 by Georg éditeur. The book covers the Order of the Solar Temple (French: Ordre du Temple solaire, OTS) a group notorious for the deaths of many of its members through both murder and suicide in several incidents throughout the 1990s. Mayer had access to many of the OTS's records while writing the book, and had been personally consulted in the police investigation.

The book analyses the beliefs of the group, as well as the psychology of its leader, and what led to the deaths. It includes many of the OTS's own documents, which make up half the book. It was later translated in two expanded editions into Italian and German, and an abbreviated English version was published as a journal article in Nova Religio. The book received positive reviews, with praise for its analysis and the attitude of the author towards its subject matter; it was described as influential on later studies of the OTS.
