Maha Sohona is a demon (yaka or yakseya) in Sinhalese folklore, who is said to haunt cemeteries. The name Maha Sohona means "great graveyard demon" or "demon of the cemetery" in the Sinhala language. It is one of the most feared demons in Sri Lanka. Originally a giant who had been defeated in a duel, Maha Sohona has had his head replaced with that of a bear since he lost his head in the duel. He is believed to kill people and afflict them with illnesses. Traditional exorcism rituals are performed to repel the demon in such cases. Sri Lanka Army's Long Range Reconnaissance Patrol units are popularly known as the "Maha Sohon Brigade", named after this demon.
