A far darrig or fear dearg 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.
They are also sometimes known as Rat Boys as they are said to be rather fat, have dark, hairy skin, long snouts and skinny tails.
[1] According to Fairy and Folk Tales of the Irish Peasantry, the far darrig is classified as a solitary fairy along with the leprechaun and the clurichaun, all of whom are "most sluttish, slouching, jeering, mischievous phantoms".
