Sharif Ali (died c. 1432) or commonly known as Sultan Berkat (the Blessed Sultan), was the fourth sultan of Brunei from 1425 until 1432, the year of his alleged death. He ascended the Brunei throne in 1425, succeeding his father-in-law, Sultan Ahmad, who had no male heir. He significantly strengthened Islam in Brunei through his various measures. His efforts not only enhanced his own stature but also benefited the entire Bruneian populace. By reinforcing Islamic principles, he further solidified the Malay Muslim Monarchic concept. As the first Sultan to construct a mosque in Brunei, he is regarded as a pious leader who governed the country in accordance with Islamic law.
