Loriot was an American sailing ship involved in exploration of the Pacific Northwest coast of North America.

[2] On November 24, 1836, the Loriot set sail from the Sandwich Islands for the Columbia River[3] with Lieutenant William A. Slacum of the U.S.

[4] Earlier in 1836 President Andrew Jackson sent Lieutenant William A. Slacum to the west coast of North America to examine San Francisco Bay, Puget Sound, and the Columbia River estuary to assess these anchorages for their strategic value.

[3] Ship and passengers arrived at the Russian settlement of Bodega on February 20, 1837, where the pioneers disembarked with Slacum then continuing on his mission.
