USS Keosauqua was a proposed United States Navy screw sloop-of-war or steam frigate that was cancelled in 1866 without being completed.
Keosauqua was a wooden-hulled bark-rigged[1] (or ship-rigged[2]) Contoocook-class screw sloop-of-war[1] or steam frigate[2] with a single funnel slated to be built for the Union Navy late in the American Civil War. She was listed in the 1864 Naval Register as "building;" her hull was projected but never completed.
Because of the collapse of the Confederate States of America in 1865, plans for her construction were cancelled in 1866. Her name was stricken from the Navy List in 1866.

- ^ a b c d Per Conway's All the World's Fighting Ships 1860–1905, p. 125, whether she would have considered a sloop or frigate depended on whether or not she would have been built with a spar deck, without which she have been a sloop, but it is unknown whether she would have had a spar deck or not because she was never built and because her completed sisters differed in this regard.
