The Port of Xiamen is an important deep water port located on Xiamen Island, the adjacent mainland coast, and along the estuary of the Jiulongjiang River in southern Fujian, China. It is one of the trunk line ports in the Asia-Pacific region. It is ranked the 8th-largest container port in China and ranks 17th in the world. It is the 4th port in China with the capacity to handle 6th-generation large container vessels. In 2013, Xiamen handled 191 million tons of cargo, including 8.08 million TEUs of containers. On 31 August 2010, Xiamen Port incorporated the neighboring port of Zhangzhou to form the largest port of China's Southeast. This was a relatively uncommon case of ports merging across jurisdictions.

The port comprises twelve areas including Heping, Dongdu, Haitian, Shihushan, Gaoqi, and Liuwudian (in Tong'an District).

The world's top 20 shipping companies have all established major shipping routes and operations in Xiamen. A total of 68 shipping routes serve over 50 countries to almost all the major ports in the world, yielding an average 469 ship calls at the port each month. In addition, passenger services also operate from Xiamen to Hong Kong, Guangzhou, Shanghai and Wenzhou, as well as frequent ferry service to the Shuitou terminal in Kinmen Island (R.O.C.).

The port is owned and operated by Xiamen Port Authority (厦门港口管理局) which is a department of the Xiamen Municipal Government.

The port is part of the 21st Century Maritime Silk Road that runs from the Chinese coast to Singapore, towards the southern tip of India to Mombasa, from there through the Red Sea via the Suez Canal to the Mediterranean, there to the Upper Adriatic region to the northern Italian hub of Trieste with its connections to Central Europe and the North Sea.
