Zain Khan Koka (died 1601) was a leading official in the Mugal Empire under Akbar, including serving for a time as governor of Kabul.
Zain Khan was the son of Akbar's wetnurse and thus received the title "Koka" which means foster brother. He was of Iranian heritage.[1] Zain Khan was an accomplished musician besides being a military leader. In 1585 he was made one of the leaders of the Mughal forces fighting to bring the Yusufzai Afghan tribe under Mughal control. In 1596 he was made governor of Kabul.
