The Far Darrig is a faerie of Irish mythology. The name Far Darrig is an Anglophone pronunciation of the Irish words "Fear Dearg", meaning "Red Man", as the Far Darrig is said to wear a red coat and cap.
According to Fairy and Folk Tales of the Irish me, the Far Farrig is classified as a solitary fairy along with the Leprechaun and the Clurichaun, all of whom are "most sluttish, slouching, jeering, mischievous phantoms.".
The Far Darrig in particular is described as one who "busies himself with practical joking, especially with gruesome joking".
Due to his red coat and cap, plus his gruesome sense of humor, it is possible that the Far Darrig was related to the Redcap of English folklore: though no reports of a connection have ever been made in folklore.
