Théophile Alajouanine (12 June 1890 – 2 May 1980) was a French neurologist.
Théophile Alajouanine was born in Verneix, Allier. He was a student of Joseph Jules Dejerine and a colleague of Georges Guillain and Charles Foix. He was a prolific writer on many topics but was particularly interested in aphasia.
Great scholar and enthusiastic bibliophile, Alajouanine privileged relationships with famous writers during his neurological career. Dostoievski's biography and works provided him with a penetrating look into the world of epilepsy.
The Laboratoire Théophile-Alajouanine, Centre hospitalier Côte-des-Neiges, Montréal is named after him.
