USS Caliph (SP-272) was a United States Navy patrol vessel in commission in 1917 and again in 1918.

Caliph was launched 20 April 1910 and was christened by Mrs. Imogene Coultes, the daughter of Commodore Brigham.

Caliph was designed by Bowes and Watts and competed in that year's Philadelphia to Havana races and placed second on the outbound journey although she had arrived first in time.

Placed in service in the 4th Naval District—which was responsible for the Pennsylvania, Delaware, and southern New Jersey area -- Caliph performed section patrol duty until December 1917, when she was laid up for the winter at Washington, D.C. Caliph was recommissioned on 1 April 1918 and assigned to duty with the District Communication Superintendent at Marcus Hook, Pennsylvania.

In 1922, Caliph was sold to Captain Robert John Luedemann of 47 Beaumont Street, Brooklyn, New York and subsequently was operated as a charter boat based in Miami, Florida until at least 1934.
