The Soviet Antarctic Expedition (SAE or SovAE) (Russian: Советская антарктическая экспедиция, САЭ, Sovetskaya antarkticheskaya ekspeditsiya) was part of the Arctic and Antarctic Research Institute of the Soviet Committee on Antarctic Research of the Academy of Sciences of the USSR. It was succeeded by the Russian Antarctic Expedition.
The Soviet Union's Ministry of Sea Transport was responsible for the administration, logistics and supply of the expeditions.
The first Soviet contact with Antarctica was in January 1947 when the Slava whaling flotilla began whaling in Antarctic waters.
