Several sultanates on the Comoros, an archipelago in the Indian Ocean with an ethnically complex mix, were founded after the introduction of Islam into the area in the 15th century. Other uses depending on the island could also be styled fani, mfaume and ntibe. Unlike sultans in many other Arab nations, these sultans had little real power. At one time alone on the island of Ndzuwani or Nzwani (today Anjouan), 40 fanis and other chiefs shared power of the island; Ngazidja (today Grand Comore) was at many times divided into 11 sultanates. This article addresses the major ones.

The term Shirazis (derived from the former Persian capital Shiraz) is a reference to Iranian roots, in some dynasties. The sultans of Hamamvu (Washirazi sultans) is a surviving dynasty that claims origins in Persia line and carries an extant connection to the Washirazi people of the East African Coast.
