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).

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.
