Trincomalee Harbour is a seaport in Trincomalee Bay or Koddiyar Bay, a large natural harbour situated on the north-east coast of Sri Lanka.
Located by Trincomalee, Sri Lanka in the heart of the Indian Ocean, its strategic importance has shaped its recent history. There have been many sea battles to control the harbour. The Portuguese, Dutch, French, and the English have each held it in turn. In 1942 the Japanese Imperial Navy attacked Trincomalee harbour and sunk three British warship anchored there.


Trincomalee Harbour, formerly a British Naval Base, was taken over by the Sri Lankan Government in 1956 to be developed as a Commercial Port. The base in Trincomalee was fitted out to perform slipway repairs for the Navy.
The harbour is being developed for bulk and break bulk cargo and port related industrial activities including heavy industries, tourism and agriculture etc. At present SLPA is in the process to re-develop Trincomalee as a metropolis growth center.


The harbour, the second largest natural harbour in the world, is overlooked by terraced highlands, and its entrance is guarded by two headlands. The harbour has 1630 hectares of water, while the entrance channel is 500 metres wide. The bay includes the first of a number submarine canyons, making Trincomalee one of the finest deep-sea harbours in the world.
