Crozier Island (Danish: Crozier Ø) is one of three islands located in the Kennedy Channel section of Nares Strait in the high Arctic.

It is part of the Avannaata municipality, Greenland.

The cliffs at its southwest side rise to a height of 60 m (200 ft) and the island is reported to be easily identified.

Crozier Island is named after the Irish-born, British naval officer Francis Rawdon Moira Crozier, second-in-command (and commander after Franklin's death) of John Franklin's ill-fated Naval Northwest Passage Expedition, 1845–1848, by Elisha Kent Kane between 1854 and 1855 during his second Grinnell Expedition, after it was sighted by Hans Hendrik and the American William Morton in June 1854.
