Kilindini Harbour is a large, natural deep-water inlet extending inland from Mombasa, Kenya. It is 25–30 fathoms (46–55 m) at its deepest center, although the controlling depth is the outer channel in the port approaches with a dredged depth of 17.5 m (57 ft). It serves as the harbour for Mombasa, with a hinterland extending to Uganda. Kilindini Harbour is the main part of the Port of Mombasa, the only international seaport in Kenya and the biggest port in east Africa. It is managed by the Kenya Ports Authority (KPA). Apart from cargo handling, Mombasa is frequented by cruise ships.
Kilindini is a Swahili term meaning "deep down" or "in the depths" in reference to the depth of the channel. Kilindini Harbor is an example of a natural geographic phenomenon called a ria, formed millions of years ago when the sea level rose and engulfed a river that was flowing from the mainland.
