Eugénie de Guérin (French pronunciation: [øʒeni də ɡeʁɛ̃]; 29 January 1805 – 31 May 1848) was a French writer and the sister of the poet Maurice de Guérin.
In her case mysticism assumed a form more strictly religious, and she continued to mourn her brother's loss of his early Catholic faith.
Five years older than he, she cherished a love for him which was blended with a somewhat motherly anxiety.
After his death she began the collection and publication of the scattered fragments of his writings.
