Hervé Guibert (14 December 1955 – 27 December 1991) was a French writer and photographer. The author of numerous novels and autobiographical studies, he played a considerable role in changing French public attitudes to HIV/AIDS.

He was a close friend of Michel Foucault. Guibert was born in Saint-Cloud, Hauts-de-Seine, to a middle-class family and spent his early years in Paris, moving to La Rochelle from 1970 to 1973. After working as a filmmaker and actor, he turned to photography and journalism.
