Leonard Oprea (; born December 16, 1953) is a Romanian novelist, poet, and essayist. In the late 1980s, he wrote two books of fiction that were banned by the Communist regime and gained him repute among dissidents. Following the 1989 Revolution, the books were published but did not attract significant notice during the political upheaval of the time. He left Romania for the United States in 1999, after which the pair of previously banned works was once again released. In the 2000s, he wrote the fictional series "Theophil Magus", and by 2020 this series included 17 separate titles. Piero Scaruffi considers his work "Cele Nouă Învățături ale lui Theophil Magus despre Magia Transilvană/ The Nine Teachings Of Theophil Magus On Transylvanian Magic" (2000) among the ten best novels in the Romanian language.
