The Khoshut (Kalmyk: Хошууд, Khoshuud) are one of the four major tribes of the Oirat people. Originally, Khoshuuds were one of the Khorchin tribes in southeastern Mongolia, but in mid 15th century they migrated to western Mongolia to become an ally of oirats to counter central Mongolian military power. Their ruling family Galwas was the Hasarid-Khorchins who were deported by the Western Mongols.

The Khoshuts first appeared in the 1580s and by the 1620s were the most powerful Oirat tribe, led others in the Buddhism conversion. In 1636 Gushi Khan led many Khoshuds to occupy Kokenuur (Qinghai), and he was enthroned as king of Tibet by the 5th Dalai Lama (see also Upper Mongols). Some time after 1645, his brother Kondeleng Ubashi migrated to the Volga, joining the Kalmyks. However, many Khoshuts remained in the Oirat homeland Zungaria under Ochirtu Setsen.

After the Zunghar leader Galdan Boshogtu Khan killed Ochirtu, the Khoshut chief Khoroli submitted to the Qing Dynasty with his people in 1686 and resettled in Alashan. They numbered 36,900 in 1990.
