The sixth USS Eagle (SP-145), later renamed USS SP-145, was an armed motorboat that served in the United States Navy as a patrol vessel from 1917 to 1919.

Eagle was built as a civilian motorboat in 1909 by J. M. Bayles and Son at Port Jefferson, New York.

The U.S. Navy acquired her from her owner, Colonel William Hester of Brooklyn, New York, on 2 May 1917 for use as a patrol vessel during World War I.

(Note that neither of these ships should be confused with patrol boat USS Eaglet (SP-909), also in commission at the time.)

SP-145 was stricken from the Navy List on 11 March 1919 and sold on 25 June 1919.
