A natural harbor is a landform where a part of a body of water is protected and deep enough to furnish anchorage. Natural harbors have long been of great strategic and economic importance. Many of the great cities of the world are located on a natural harbor. Having a protected harbour reduces or eliminates the use of breakwaters as it will result in calmer waves inside the harbour.

Sometimes a harbor is needed where one isn't available due to damage, such as in times of war. In this case a temporary harbor may be built and transported in pieces to the location. The most notable of these were the two Mulberry harbours used during the D-Day invasion of Normandy in World War II.
