Nizam al-Din Shami, also known as Nizam-i Shami or Nizam al-Din Shambi (died before 1409 or before 1411-1412), was a Persian man of letters and a chronicler who flourished in the late 14th and early 15th centuries. He wrote the Zafarnama, the earliest extant Timurid chronicle and the oldest surviving biography on Timur (r. 1370–1405). Shami's Zafarnama was continued by Hafiz-i Abru (died 1430), and would also form the basis of the better-known Zafarnama of Sharaf al-Din Ali Yazdi (died 1454).
