Maritime history of Somalia refers to the seafaring tradition of the Somali people. It includes various stages of Somali navigational technology, shipbuilding and design, as well as the history of the Somali port cities. It also covers the historical sea routes taken by Somali sailors which sustained the commercial enterprises of the historical Somali kingdoms and empires, in addition to the contemporary maritime culture of Somalia.
In antiquity, the ancestors of the Somali people were an important link in the Horn of Africa connecting the region's commerce with the rest of the ancient world. Somali sailors and merchants were the main suppliers of frankincense, myrrh and spices, items which were considered valuable luxuries by the Ancient Egyptians, Phoenicians, Mycenaeans and Babylonians. During the classical era, several ancient city-states such as Ophir at the time Berbera and Ras Hafun and Hiran then part of Mogadishu competed with the Sabaeans, Parthians and Axumites for the wealthy Indo-Greco-Roman trade also flourished in Somalia. In the Middle Ages, several powerful Somali empires dominated the regional trade including the Ajuran Sultanate, the latter of which maintained profitable maritime contacts with Arabia, India, Venetia, Persia, Egypt, Portugal and as far away as China. This tradition of seaborne trade was maintained in the early modern period, with Berbera being the pre-eminent Somali port during the 18th–19th centuries.
