USS Narada (SP-161) was an 1889 Scottish-built steam yacht, originally Semiramis and later named Margarita, that served in the United States Navy as a patrol vessel from 1917 to 1919.

[1] She was launched on 30 May 1889 as Semiramis, the legendary ruler of Assyria, for John Lysaght of Bristol, a steel company owner, who had previously bought two smaller yachts from the same shipyard.

[2] She measured 491 GRT and 272 NRT and was powered by a 725-indicated-horsepower (541 kW) triple expansion steam engine, made by the shipbuilder and driving a single screw.

[1][4] In September 1892, John Lysaght returned to Ramage & Ferguson and ordered an even larger yacht, named Cleopatra, and sold Semiramis.

In an attempt to lure him away from Paris and extravagant expenditure founded on debt, she planned a long cruise, in the company of a young scientist, Louis Lapicque; the son refused to go, and Semiramis eventually sailed for the Indian Ocean without him in November 1892.
