Atanatar II is a fictional character in J. R. R. Tolkiens universe of Middle-earth

He succeeded his father Hyarmendacil I in 1149 T.A. as the sixteenth King of Gondor. He was known as Atanatar II Alcarin, the Glorious, for Gondor enjoyed its greatest wealth and power under him.

His wealth was so great that precious stones are pebbles in Gondor for children to play with.

The deeds of Atanatar weren't as "Glorious" as his nickname would indicate. He made no effort to expand or maintain the power of his father and the guard on Mordor was neglected. So therefore his reign is seen as the start of Gondor's final decline before the War of the Ring.

He was succeeded by his son Narmacil I in 1226 T.A.
