Admiral Sir Benjamin Hallowell Carew GCB, (born Benjamin Hallowell) (?1 January 1761-2 September 1834) was a senior officer in the Royal Navy. He was one of the select group of officers, referred to by Nelson as his "Band of Brothers", who served with him at the Battle of the Nile.

Hallowell is probably best known as the man who made Nelson a present of what would become his own coffin, after the Battle of the Nile in August 1798. Hallowell commanded HMS Swiftsure during the battle, a 74-gun ship of the line which bombombarded the French flagship L'Orient at close quarters and played a major role in her destruction. Some time later he sent Nelson a coffin he had ordered to be made from a salvaged piece of L'Orient's mainmast, with an accompanying note:

"Sir, I have taken the liberty of presenting you a coffin made from the main mast of L'ORIENT, that when you have finished your military career in this world you may be buried in one of your trophies. But that that period may be far distant is the earnest wish of your sincere friend, Benjamin Howell"
