The Port of Odesa or Odesa Sea Port, located near Odesa, is the largest Ukrainian seaport and one of the largest ports in the Black Sea basin, with a total annual traffic capacity of 40 million tonnes, the only port of Ukraine capable of accepting Panamax class vessels. The port has an immediate access to railways allowing quick transfer of cargo from sea routes to ground transportation. Along with its younger satellite ports of Chornomorsk (1958) and Yuzhne (1973), the Port of Odesa is a major freight and passenger transportation hub of Ukraine.

Odesa is the third most populous city and municipality in Ukraine and a major seaport and transport hub located in the south-west of the country, on the northwestern shore of the Black Sea. The city is also the administrative centre of the Odesa Raion and Odesa Oblast, as well as a multiethnic cultural centre. As of January 2021, Odesa's population was approximately 1,010,537. On 25 January 2023, its historic city centre was declared a World Heritage Site and added to the List of World Heritage in Danger by the UNESCO World Heritage Committee in recognition of its influence on cinema, literature, and the arts. The declaration was made in response to the bombing of Odesa during the Russian invasion of Ukraine, which has damaged or destroyed buildings across the city.
