Bādī II Abū Daqn, known as The Bearded (r. 1644/5 – 1681), was a ruler of the Kingdom of Sennar (also known as the Funj Sultanate). He was the son of Rabat I and ascended to the throne in 1644/5.
During the reign of Badi II, the Kingdom of Taqali to the west was defeated and made a vassal state. He captured northern and western parts of Kordofan and extended Funj territory across the White Nile, occupying the northern half of the Shilluk Kingdom in 1650 and defeating the Abdallabi tribes who were supported by the Ottoman Empire. He defeated the Darfur Sultan Musa by the mid-1650s and reduced the tribal chieftaincies northward along the Nile to feudatories.
Under Badi II, Sennar became the fixed capital of the Funj Sultanate. During his reign written documents concerning administrative matters first appeared, with the oldest known dating to 1654.
Badi II died in 1681. He was succeeded by Unsa II.
