USS Shrewsbury (SP-70) was an armed motorboat that served in the United States Navy as a patrol vessel from 1917 to 1919.

Shrewsbury was built in 1910 by George Lawley & Son at Neponset, Massachusetts, as the private motorboat Mona.

In private use, she subsequently was renamed Gipsy (according to one source),[5] then Topsy.

She had been renamed Shrewsbury by the time the U.S. Navy acquired her from her owner, N. H. McCarter of Newark, New Jersey, on 13 April 1917 for World War I service.

Shrewsbury patrolled in the 4th Naval District along the central United States East Coast during World War I.
