Vostok (Boctok or East) was a single-seat crewed spacecraft built by the Soviet Union. It carried the first human, Yuri Gagarin, into space on April 12, 1961.

Six crewed flights were made between 1961 and 1963. A modified version called Voskhod carrying three cosmonauts flew two further missions when it was replaced by the Soyuz spacecraft, which is still in use today.
