Nadezhda (or Nadeshda, or Nadeshada ) was a three-masted sloop, the ex-British merchantman and slave ship Leander, launched in 1799.

[2] The 1800 and 1801 editions of Lloyd's Register showed her launch year as 1799, Anderson as her master, T. Huggins as her owner, and her trade as London-Africa.

[3] She never arrived at London because on 17 January 1801, a French privateer of 22 guns and 160 men captured Leander as she approached England.

In 1802 Yuri Fydorovich Lisyansky purchased Leander and another merchantman, Thames, for his planned voyage of exploration.

The two ships took part in the first Russian circumnavigation of the world, with Nadezhda serving as Admiral Krusenstern's flagship.

[9] The expedition failed, however, to achieve two of its main goals, to establish diplomatic relations with Japan, and to secure trading rights to Canton.

[7] Krusenstern and Captain Yury Nevelskoy of Neva prepared for the voyage by first serving with the British Royal Navy from 1793 to 1799 to build their naval skills.

As part of her circumnavigation she delivered RAC cargo to Kamchatka, and the first Russian embassy under Nikolai Rezanov to Japan.

[11] One passenger aboard Nadezhda was Fabian Gottlieb von Bellingshausen, who between 1819 and 1821 would lead a second Russian circumnavigation of the world.

In 1808 an American merchant, D. Martin, chartered Nadezhda to transport RAC cargoes from Kronstadt to New York City.
