The Djiboutian Navy (French: Marine Nationale Djiboutienne, Somali: Ciidanka Badda Jabuuti) is the naval service branch of the Djibouti Armed Forces.

Through joint exercises and humanitarian missions, including disaster relief, the Djiboutian Navy promotes bilateral relations between nations.

It has a fleet of gunboats, fast missile boats and support, training, which can be deployed to defend the territorial waters and coastline of Djibouti as well as protect tankers passing through the Bab-el-Mandeb strait.

The navy was built and structured with assistance from the United States since the end of the Cold War, but has also relied on other sources for equipment in some areas.

The acquisition of the several boats from the US in 2006 considerably increased the navy's ability to patrol over longer distances and to remain at sea for several days at a time.
