The Shahnameh or Shah-nama (Persian: شاهنامه‎ Šāhnāmeh, "The Book of Kings") is a long epic poem written by the Persian poet Ferdowsi between c. 977 and 1010 AD and is the national epic of Iran and related societies. Consisting of some 60,000 verses, the Shahnameh tells mainly the mythical and to some extent the historical past of (Greater) Iran from the creation of the world until the Islamic conquest of Persia in the 7th century.

The work is of central importance in Persian culture, regarded as a literary masterpiece, and definitive of ethno-national cultural identity of Iran. It is also important to the contemporary adherents of Zoroastrianism, in that it traces the historical links between the beginnings of the religion with the death of the last Zoroastrian ruler of Persia during the Muslim conquest.

Ferdowsi started writing the Shahnameh in 977 A.D and completed it on 8 March 1010. The Shahnameh is a monument of poetry and historiography, being mainly the poetical recast of what Ferdowsi, his contemporaries, and his predecessors regarded as the account of Iran's ancient history. Many such accounts already existed in prose, an example being the Shahnameh of Abu-Mansur Daqiqi. A small portion of Ferdowsi's work, in passages scattered throughout the Shahnameh, is entirely of his own conception.
