USS Arcady (SP-577) was a United States Navy patrol vessel in commission from 1917 to 1919.

Arcady was built as the private steam yacht Osceola by Samuel H. Pine at New York City.

On 28 May 1917, the U.S. Navy purchased Arcady from her owner, Arthur Meeker of Beverly, Massachusetts, for use as a section patrol vessel during World War I.

In October 1918, Arcady was reassigned to the 2nd Naval District in southern New England, where she performed patrol duty from her base at Submarine Base New London at New London, Connecticut, through the end of World War I and into the spring of 1919.

She was stricken from the Navy List on 17 May 1919 sold to Mr. C. R. Stewart of Arlington, New Jersey, on 20 September 1919.
