Port Sudan (Arabic: بور سودان) is a port city in eastern Sudan, and the capital of the state of Red Sea. As of 2007, it has 489,725 residents. Located on the Red Sea, it is recognized as Sudan's main seaport and the source of 90% of the country's international trade. Port Sudan was built between 1905 and 1909 by the administration of Anglo-Egyptian Sudan to replace Suakin. An oil pipeline was built between the port and Khartoum in 1977.
In 2020, Russian president Vladimir Putin announced that the Russian Navy would begin construction on a base with capacity for 300 personnel and four warships in Port Sudan. The facility would prove Russia with a naval base in the nation for at least 25 years. The plan was ultimately suspended, though Sudanese leadership indicated that it is possible for the construction to go forward in the future.
Following the October-November 2021 Sudanese coup d'état, the Beja tribal council initiated a weeklong blockade of the city's ports. Following negotiations with military officials, the blockade was lifted.
