The Red Hand of Ulster (Irish: Lámh Dhearg Uladh) is a symbol used in heraldry[1] to denote the Irish province of Ulster and the Northern Uí Néill in particular. It has also been used however by other Irish clans across the island, including the ruling families of western Connacht (i.e. the O'Flahertys and McHughs) and the chiefs of the Midlands (e.g. O'Daly, Kearney, etc.).[2]
It is an open hand coloured red, with the fingers pointing upwards, the thumb held parallel to the fingers, and the palm facing forward. It is usually shown as a right hand, but is sometimes a left hand, such as in the coats of arms of baronets.
