In Irish mythology, Nuada or Nuadu (modern spelling: Nuadha), known by the epithet Airgetlám (modern spelling: Airgeatlámh, meaning "silver hand/arm"), was the first king of the Tuatha Dé Danann. He is cognate with the Gaulish and British god Nodens. His Welsh equivalent is Nudd or Lludd Llaw Eraint.
Nuada was king of the Tuatha Dé Danann for seven years before they came to Ireland. They made contact with the Fir Bolg, the then-inhabitants of the island, and Nuada sought from them half of the island for the Tuatha Dé, which their king rejected. Both peoples made ready for war, and in an act of chivalry allowed their numbers and arms to be inspected by the opposing side to allow for a truly fair battle. During this first great battle at Mag Tuired, Nuada lost an arm in combat with the Fir Bolg champion Sreng. Nuada's ally, Aengaba of Norway, then fought Sreng, sustaining a mortal wound, while the Dagda protected Nuada. Fifty of the Dagda's soldiers carried Nuada from the field. The Tuatha Dé gained the upper hand in the battle, but Sreng later returned to challenge Nuada to single combat. Nuada accepted, on the condition that Sreng fought with one arm tied up. Sreng refused, but by this point the battle was won and the Fir Bolg all but vanquished. The Tuatha Dé then decided to offer Sreng one quarter of Ireland for his people instead of the one half offered before the battle, and he chose Connacht.
Having lost his arm, Nuada was no longer eligible for kingship due to the Tuatha Dé tradition that their king must be physically perfect, and he was replaced as king by Bres, a half-Fomorian prince renowned for his beauty and intellect. The Fomorians were mythological enemies of the people of Ireland, often equated with the mythological "opposing force" such as the Greek Titans to the Olympians, and during Bres's reign they imposed great tribute on the Tuatha Dé, who became disgruntled with their new king's oppressive rule and lack of hospitality. By this time Nuada had his lost arm replaced by a working silver one by the physician Dian Cecht and the wright Creidhne (and later with a new arm of flesh and blood by Dian Cecht's son Miach). Bres was removed from the kingship, having ruled for seven years, and Nuada was restored. He ruled for twenty more years.
Bres, aided by the Fomorian Balor of the Evil Eye, attempted to retake the kingship by force, and war and continued oppression followed. When the youthful and vigorous Lugh joined Nuada's court, the king realised the multi-talented youth could lead the Tuatha Dé against the Fomorians, and stood down in his favour. The second Battle of Mag Tuired followed. Nuada was killed and beheaded in battle by Balor, but Lugh avenged him by killing Balor and led the Tuatha Dé to victory.
Nuada may be the same figure as Elcmar, and possibly Nechtan. Other characters of the same name include the later High Kings Nuadu Finn Fáil and Nuadu Necht, and Nuada, the maternal grandfather of Fionn mac Cumhaill. A rival to Conn of the Hundred Battles was Mug Nuadat ("Nuada's Slave"). The Delbhna, a people of early Ireland, had a branch called the Delbhna Nuadat who lived in County Roscommon. The present day town of Maynooth in County Kildare is named after Nuada (its Irish name is Maigh Nuad, meaning The plain of Nuada).
Mythological parallels 
Nuada's name is cognate with that of Nodens, a Romano-British deity associated with the sea and healing who was equated with the Roman Mars, and with Nudd, a Welsh mythological figure. It is likely that another Welsh figure, Lludd Llaw Eraint (Lludd of the Silver Hand), derives from Nudd Llaw Eraint by alliterative assimilation. (The Norse god Týr is another deity equated with Mars who lost a hand).
The name Nuada probably derives from a Celtic stem *noudont- or *noudent-, which J. R. R. Tolkien suggested was related to a Germanic root meaning "acquire, have the use of", earlier "to catch, entrap (as a hunter)". Making the connection with Nuada and Lludd's hand, he detected "an echo of the ancient fame of the magic hand of Nodens the Catcher". Similarly, Julius Pokorny derives the name from a Proto-Indo-European root *neu-d- meaning "acquire, utilise, go fishing".
- Or a hand - Old Irish lám can mean either. The First Battle of Mag Tuired (§48) specifically says that Sreng "severed his right arm at the shoulder; and the king’s arm with a third of his shield fell to the ground".
