James Fitzjames (27 July 1813 – c.?1848) was a British Royal Navy officer who participated in two major exploratory expeditions, the Euphrates Expedition and the Franklin Expedition.
He was of illegitimate birth, and during his life and after his friends and relatives took great pains to conceal his origins.
It has been suggested his true father was Sir James Gambier, although the identity of his mother remains unknown.
