Sir Edward Augustus Inglefield (27 March 1820 – 4 September 1894) was a Royal Naval officer who led one of the searches for the missing Arctic explorer John Franklin during the 1850s. In doing so, his expedition charted previously unexplored areas along the northern Canadian coastline, including Baffin Bay, Smith Sound and Lancaster Sound. He was also the inventor of the marine hydraulic steering gear and the anchor design that bears his name. The warship HMS Inglefield is named after him, as is the Inglefield Land region of Greenland.
