Francis Rawdon Moira Crozier FRS FRAS (/ˈkroʊʒər/; 17 October 1796 – disappeared 26 April 1848) was an Irish officer of the Royal Navy and polar explorer who participated in six expeditions to the Arctic and Antarctic.

[2] He, with James Clark Ross and Richard Moody, was also responsible for selecting the location of the capital of the Falkland Islands, Port Stanley, in 1843.

He was the eleventh of thirteen children, and the fifth son of solicitor George Crozier, who named him after his friend Francis Rawdon-Hastings, 2nd Earl of Moira.

Crozier was promoted to lieutenant in 1826, and a year later, he once more joined Parry in his attempt to reach the North Pole; ultimately a futile endeavour.

Crozier joined Clark Ross as second-in-command of HMS Cove in 1835, to assist in the search for 12 lost British whaling ships in the Arctic.

[10] Inuit rumours collected between 1852 and 1858 indicate that Crozier and one other expedition member might have been seen in the Baker Lake area, about 400 km (250 mi) to the south, where, in 1948, Farley Mowat found "a very ancient cairn, not of normal Eskimo construction", inside which were fragments of a hardwood box with dovetail joints.

In 2014, the Victoria Strait Expedition found two items on Hat Island, in the Queen Maud Gulf, near King William Island; part of a boat-launching davit bearing the stamps of two Royal Navy broad arrows, and a wooden object, possibly a plug for a deck hawse, the iron pipe through which the ship's chain cable would descend into the chain locker below.

In January 2008, Crozier's home town of Banbridge hosted a memorial event, which included a service of remembrance and thanksgiving at the Church of the Holy Trinity, which was attended by more than a hundred descendants of Crozier and other officers of Franklin's lost expedition and those who searched for it, along with the chairman of Banbridge Council, and several Arctic historians, including Michael Smith and Russell Potter.

[19] A memorial to Sir John Franklin and his men was erected by order of Parliament in 1858, in the Painted Hall of London's Greenwich Hospital.
