Newfie (also Newf or sometimes Newfy) is a colloquial term used in Canada for someone who is from the maritime provinces of Canada, specifically but not exclusive to Newfoundland. It appears in a 1942 dictionary of slang; at the time, 'Newfie' was used as often to refer to Newfoundland itself as to people from Newfoundland (who were also 'Newfiers'). The term 'Newfie' has been applied to the Newfoundland people, the proper demonym for whom is Newfoundlander(s). It also can refer to items of Newfoundland origin such as:
- Newfie Bullet, a nickname created by U.S. military personnel serving at bases in Newfoundland during the Second World War for a notoriously slow passenger train operated on the island.
- Newfie Screech, a type of rum bottled in Newfoundland.
- Relatedly, Newfiejohn was the name used by some sailors for St. John's (the capital) while on convoy duty during the Second World War. 
The first edition of the Gage Canadian Dictionary, published in 1983, and the second edition of the Random House Unabridged Dictionary, published in 1987, both include usage notes describing the term 'Newfie' as offensive. However, neither the second edition of the Canadian Oxford Dictionary, published in 2004, or the current edition of the Dictionary of Newfoundland English, published in 1998, make such a mention.
In the 1970s, the Government of Alberta added the term 'Newfie' to a list of words not allowed to be used on personalised licence plates, reasoning that it was an ethnic slur and hateful. In 2006, a man from Newfoundland argued that it was also a source of pride, and fought to have the word removed from the list, and he eventually won. As of 2008, the ban has been lifted.
