Ahmad (born Awang Pateh Berbai; died c.1425), also known as Pateh Berbai, was the third sultan of Brunei from 1408 until his death in 1425. He was the eldest son of Dewa Amas Kayangan and the brother of Awang Alak Betatar (also known as Muhammad Shah of Brunei). It was under him that the kingdom adopted the name Brunei, this ascribed him as the founder of Brunei in the Syair Awang Semaun (Poem of Awang Semaun). Islamic education is thought to have begun in the country during the rule of his predecessor and continued under him.
