Ilse Esther Hoffe (8 May 1906 – 2 September 2007) was a Jewish woman known for being the secretary and presumed mistress of writer Max Brod. Upon his death in 1968, she received a large trove of materials relating to Franz Kafka, Brod's friend. Some of these were sold but most were controversially passed, unreleased to the public, to her two daughters after her own death. She was born in Troppau (Opava).
