Necho (nēˈkō) [key], fl. 670 B.C., lord of Saïs, Egypt. He was confirmed in his holding after the Assyrian conquest in 670; he was later taken to Nineveh in chains for plotting to revolt but was pardoned and restored. He probably fell opposing (663) the Nubian reconquest under Tanutamon. His son Psamtik founded the XXVI dynasty.
