Maḥmūd bin Muḥammad bin Tīmūr Khān (Turki and Persian: محمود بن محمد بن تیمور خان), also known as Mahmud Astrakhani (Tatar: Ästerxannıñ Mäxmüd) was one of Küchük Muhammad's sons and a Khan who founded the Khanate of Astrakhan in the 1460s.
His letter to the Ottoman Sultan Mehmed II (as dispatched on April 10, 1466) is a curious example of diplomatic epistles written in Persian or in the 15th-century Old Tatar language. The content is a necessity of establishment of diplomatic relations between Ottoman Empire and Astrakhan, and sending ambassadors to Istanbul.
For uncertainties and additional information see the second part of List of Astrakhan khans.
His son Janibeg briefly ruled Crimea in the winter of 1476/77 until he was driven out by the legitimate ruler Nur Devlet.
