Based on the similarities of heroic-themed narratives, the Monomit theory created by Campbell guides us in understanding and evaluating the commonalities of myths and other narratives today. Monomit theory consists of the departure, initiation and return which eventually explains the return of a hero as a hero, namely his birth. In this study, the folk tale of Lover Mevlut Ihsani called Bedri Sinan and Mahperi was examined and tried to be understood within the framework of monomit theory. The aim is to determine the extent to which monomit theory applies to Turkish folk narratives and to determine different situations. The reasons for choosing The Mahperi Story with Bedri Sinan are; the fact that the story is a long folk tale, the diversity of building elements such as person and place, can be listed as many small events connected to the main story enrich the story during the narrative. The text used in the review was taken from the study "A Research on The Stories of Love Mevlut Ihsani" prepared by Prof. Dr. Işıl ALTUN. As a result of the investigation; call to adventure, supernatural aid, crossing the first threshold, the belly of the whale, the road of the trials, ultimate boon, magic escape, help from outside, when determining characteristics that meet the criteria of two world masters; narratives appropriate to refusal of the call, the meeting with the goddess, woman as the temptress, atonement with the father, apotheosis and refusal of the return have not been determined. In this sense, while the story in question largely complies with the monomit theory, it has been seen that it diverges from the theory at some points for reasons such as cultural values and censorship.
