Alexandre Jacques François Brière de Boismont (often translated as Brierre de Boismont in English) (18 October 1797 – 25 December 1881) was a French physician and psychiatrist born in Rouen.

In 1831 he performed important studies of a cholera epidemic in Poland, and in 1838 was appointed director of a private nursing home on Rue Neuve Sainte-Genevieve, located near the Panthéon de Paris.

Brière de Boismont was the author of numerous publications in several medical fields, that included hygiene, forensic medicine and anatomy, but is best known for his work in psychiatry.

This book was later translated into English as Hallucinations: or, The rational history of apparitions, dreams, ecstasy, magnetism, and somnambulism (1853).

In 1862, Brière de Boismont provided an early description of what would later become known as Kleine-Levin syndrome (KLS).
