Safar ud-Din al-Qasim bin Sulaiman (Arabic: صفر الدين القاسم بن سليمان) or Safaruddin Alkaseem Anak Sulayman (Jawi: سافارو الدين الكاسيم انق سوليم) and later Don Enrique de Safaruddín y Alkázim (Enrique Safaruddin in short) was the Sixth Sultan of Maynila from 1640-1680 and the Provincial Governor of Manila from 1670-1690, the longest reigning sultan of Manila. He was also the first native to ever become a provincial governor, an extremely high rank not available to the other members of the native nobility.
