The Tümed (Mongolian: Түмэд; Chinese: 土默特部; "The many or ten thousands" derived from Tumen) are a Mongol subgroup. They live in Tumed Left Banner, district of Hohhot and Tumed Right Banner, district of Baotou in China. Most engage in sedentary agriculture, living in mixed communities in the suburbs of Hohhot. Parts of them live along Chaoyang, Liaoning. There are the Tumeds in the soums of Mandal-Ovoo, Bulgan, Tsogt-Ovoo, Tsogttsetsii, Manlai, Khurmen, Bayandalai and Sevrei of Ömnögovi Aimag, Mongolia.
From the beginning of the 9th century to the beginning of the 13th century, the Khori-Tumed lived near the western side of Lake Baikal. They lived in what is now southern Irkutsk Oblast, in some parts of Tuva and in southwestern Buryatia. In 1207, Genghis Khan, after conquering the Khori-Tumed, decided to move some of these groups south and these people eventually settled in the southern parts of the Great Gobi Desert. But it seems that the Tumed people had no strong connection with those forest people in Siberia.
