The New Caledonia Barrier Reef(新喀里多尼亚堡礁)is located in New Caledonia in the South pacific, and is the second—longest coral reef in the world, after Australia’s Great Barrier Reef.

   The New Caledonian Barrier reef surrounds Grande Terre, New Caledonia's largest island, as well as the Ile des Pins and several smaller islands, reaching a length of 1,500 km. The reef encloses (围住)in a lake of 24,000 square kilometers, which has an average depth of 25 meters. The reefs lie up to 30 kilometers from the shore, but extend almost 200 km to the Entrecasteaux reefs in the northwest. This northwestern extension encloses the Belep Islands . Several natural passages open out to the ocean. The Boulari passage, which leads to Noumea, the capital and chief port of New Caledonia, is marked by the Amédée lighthouse.

The reef has great species diversity with a high level of endemism(动植物的特有分布), and is home to endangered dugongs , a kind of sea animal, and is an important nesting site for Green Sea Turtle.

Most of the reefs are generally thought to be in good health. Some of the eastern reefs have been damaged by wastewater from nickel mining (镍开采)on Grand Terre. The waste from mining, agriculture, and grazing(开放) has affected reefs near river mouths, which has been worsened by the destruction of mangrove forests, which help to keep wastes. Some reefs have been buried under several meters of wastes.

In the lagoons of New Caledonia there are many water species ranging from plankton to larger fish and even sharks.

In January 2002, the French government proposed(提议) listing New Caledonia's reefs as a UNESCO World Heritage Site. UNESCO listed New Caledonia Barrier beef on the World Heritage List on 7 July 2008.
