Manggūltai (Manchu: ᠮᠠᠩᡤᡡᠯᡨᠠᡳ, Möllendorff: Manggūltai, Abkai: Manggvltai; Chinese: 莽古爾泰; 1587 – 11 January 1633) was a Manchu noble and an important military and political leader in the early years of the Qing dynasty.
Manggūltai was born in the Manchu Aisin Gioro clan as the fifth son of Nurhaci, the founder of the Qing dynasty.
Starting in 1621, Manggūltai and the other three senior beiles served as assistants to Nurhaci on a monthly rotational basis in directing state affairs of the Later Jin dynasty.
After Nurhaci's death, Daišan used his influence to make the princes and generals to agree on Hong Taiji's accession as Khan.
Although Hong Taiji had become Khan, Manggūltai, along with Daišan and Amin continued to take turns as assistant administrators until 1629, when Hong Taiji had begun to consolidate power.
