The Madrasa of Amir Sunqur Sa'di, also commonly known as the Mausoleum of (Sheikh) Hasan Sadaqa, is a medieval Mamluk-era madrasa structure and mausoleum in Cairo, Egypt. It was originally built between 1315 and 1321 CE by amir Sunqur Sa'di. Sunqur was forced to leave Egypt in his lifetime and was never buried there, but a sheikh known as Hasan Sadaqa was later buried in it and therefore the building is often known by his name. From the 17th century onward the complex was converted into Mevlevi Sufi lodge and is open today as the Mawlawiyya Museum or Museo Mevlevi.
