USS Endion (SP-707)

USS Endion (SP-707) was a United States Navy patrol vessel in commission from 1917 to 1919.

Endion was built as a private motorboat of the same name in 1898. On 1 May 1917, the U.S. Navy purchased her for use as a section patrol boat during World War I. She was commissioned the same day as USS Endion (SP-707) with Chief Boatswain's Mate F. R. Neal, USNRF, in command.

Assigned to the 1st Naval District in northern New England, Endion carried out patrol duties for the rest of World War I.

Endion was stricken from the Navy List on 6 October 1919 and subsequently sold.
