USS Oceanographer (AGS-3) was a survey ship of the United States Navy during World War II that produced charts chiefly of passages in the Solomon Islands area of the Pacific Ocean. Upon transfer to the Navy, she had initially been named and classed as gunboat USS Natchez (PG-85). Before her World War II Navy service, she had been USC&GS Oceanographer (OSS-26), a survey ship with the U.S. Coast and Geodetic Survey from 1930.

From her launch in 1898 to 1930, she had been Corsair III, a private steam yacht of American industrialist J. P. Morgan, Jr., except for a brief period during World War I. During that conflict, the United States Navy chartered her as patrol vessel USS Corsair (SP-159). She accompanied the American Expeditionary Force to France in 1917 and patrolled off the west coast of that country.

After putting in for needed repairs in June 1944, Oceanographer, after further inspection, was instead decommissioned in September and broken up for scrap.

Corsair, designed by John Beavor-Webb, was built in 1898 by T. S. Marvel Shipbuilding, Newburgh, New York, christened by the daughter of the owner, Miss. Louise Morgan, and her hull launched in December 1898. Her triple expansion steam engines were fitted by W. & A. Fletcher Co. of Hoboken, New Jersey after launch.

Corsair was chartered by the Navy 15 May 1917; commissioned the same day, Lieutenant Commander T. A. Kittinger in command; and reported to the Atlantic Fleet.
