MV John Paul DeJoria (formerly USCGC Block Island (WPB-1344)) was a former United States Coast Guard cutter owned and operated by the Sea Shepherd Conservation Society.

Until scrapped, she was used in their direct action campaigns against illegal fisheries activities.

[3] In January 2015, Sea Shepherd purchased two decommissioned Island-class patrol boats from the United States Coast Guard, capable of a top speed of 30 knots (56 km/h; 35 mph).

[3] They were joined by another ex-USCG island class cutter in December 2017, the MV Sharpie.

[5][6] Under the new name, the ship's first mission was to join the search for the missing filmmaker Rob Stewart in the Florida Keys.
