Порт-Судан: от торгового порта к фактической столице Судана.

Port Sudan (بور سودان, Beja: Bar'uut) is a city and port on the Red Sea in eastern Sudan, and the capital of Red Sea State. Port Sudan is Sudan's main seaport and the source of 90% of the country's international trade. The population of Port Sudan was estimated in the 2008 Census of Sudan to be 394,561 people. Port Sudan has historically been a center for commercial activity, particularly in the shipping industry. An oil pipeline was built between the port and Khartoum in 1977.

In 2009, Israel allegedly used naval commandos to attack Iranian arms ships at Port Sudan as part of Operation Birds of Prey. 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 provide Russia with a naval base in the nation for at least 25 years. The plan was ultimately suspended, though Sudanese leadership has indicated that it is possible for the construction to go ahead in the future. In 2016, it was reported that residents of Port Sudan face water scarcity. 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.

During the 2023 Sudan war, Port Sudan has emerged as a leading destination and refuge for internally displaced persons fleeing war in other parts of the country. Internally displaced refugees in the city reportedly face extreme heat and shortages of food and water. By late October 2023, Reuters reported that the Rapid Support Forces (RSF) controlled most of Khartoum, causing the government led by Abdul Fattah el Burhan to have largely relocated to Port Sudan. General Abdul Fattah al Burhan, leader of the Sudanese Armed Forces, "has threatened to establish a cabinet at the Red Sea city of Port Sudan, with the intention of creating an alternative or second capital." Hemedti, leader of the RSF, in turn, warned that this would lead to him declaring his own rival government based in Khartoum or another city he controlled. Analysts have raised concerns of a lasting split similar to that of Libya during its civil wars. Port Sudan has been described as becoming a "de facto" capital of Sudan.

The city has an oil refinery and handles 90% of the country's international trade. The main airport is Port Sudan New International Airport. There is now a tarred road linking Port Sudan to Khartoum via Atbara. Port Sudan also has a 1067mm gauge rail link with Khartoum. There is also an international ferry from Jeddah. In 2023 a new seaport was proposed about 200km north of Port Sudan at Abu Amama. A 450km road to the farming hub at Abu Hamad would also be provided. This new seaport is opposite Jeddah which shortens the ferry trip from Jeddah.

The city is home to the Red Sea University, established in 1994.

Places of worship are predominantly Muslim mosques, but there are also Christian churches and temples including the Roman Catholic Archdiocese of Khartoum (Catholic Church), Sudan Interior Church (Baptist World Alliance), and Presbyterian Church in Sudan (World Communion of Reformed Churches) and Coptic Orthodox Churches.

Port Sudan has a hot desert climate (Köppen: BWh) with extremely hot summers and moderately hot winters, requiring the acquisition of fresh water from Wadi Arba'at in the Red Sea Hills and from salt evaporating pans. Temperatures can easily exceed 30 °C (86 °F) in winter and 45 °C (113 °F) in summer. Over 90% of the annual rainfall falls between October and January, mostly in November, with the wettest month on record being November 1947 with , whilst the wettest year was from July 1923 to June 1924 with Average annual rainfall is , and no rainfall occurred between January 1983 and June 1984. The mean temperature year round (the average of all daily highs and nighttime lows) is 28.4 °C (83 °F).
