In J. R. R. Tolkien's literary works, the House of Elendil is the House from which the Kings of Arnor and Gondor were descended. The House of Elendil was born out of the ashes of the House of Andúnië which in turn was descended from the Royal House of Númenor, the House of Elros, thus making the Kings of Arnor and Gondor Half-elven.
