Charles-Albert Demoustier (13 March 1760 – 2 March 1801) was a French writer.
He falsely claimed to be a descendant of La Fontaine by his mother and Racine by his father.
Demoustier was born in Villers-Cotterêts.
He worked as a lawyer, but later decided to become a writer.
In 1786, he published the first part of Lettres à Emilie sur la mythologie.
The sixth part was published in 1798.
These works, alternating prose and madrigal-like verses, were very successful.
Demoustier tried to edit Lettres à Emilie sur la mythologie, but the bookseller who owned the copyrights refused to let him do so, perhaps because he had a stock of earlier copies he wanted to get rid of first.
