"Cod Liver Oil" is a song about a traditional medicinal drink for many Newfoundlanders. Cod liver oil in the traditional way of manufacture was sun cured and served in bottles in its raw form. The song was written by Johnny Burke (1851–1930), a balladeer from St. John's, Newfoundland. It has been recorded by the Irish band The Dubliners and by Newfoundland folk rock Band Great Big Sea on their album The Hard and the Easy.
