Bungi /ˈbʌn.ɡi/ (also called Bungee, Bungie, Bungay, Bangay, or the Red River Dialect) is a dialect of English with substratal influence from Scottish English, the Orcadian dialect of Scots, Norn, Scottish Gaelic, French, Cree, and Western Ojibwe. It was spoken by the Scottish Red River Métis in present-day Manitoba, Canada, and formerly in areas of Ontario and Minnesota, United States.

Bungi has been categorized as a post-creole, with the distinctive features of the language gradually abandoned by successive generations of speakers in favour of standard Canadian English. In 1870, about 5,000 Métis were native speakers of Bungi, but by the late 1980s, only a handful of elderly speakers were known. Today, Bungi has very few if any speakers and is potentially extinct.

Bungi was spoken in the Lower Red River Colony in the area from The Forks (where the Red River and Assiniboine River meet in what is now downtown Winnipeg) to the mouth of the Red River at Lake Winnipeg. This is the area where the English/Scottish retired Hudson's Bay Company servants generally settled.

Over the years, Bungi has been spelled many different ways by many different people, and was often referred to simply as the Red River Dialect. Expanded scholarship has preferred "Bungi" as the preferred spelling over "Bungee" and other spellings.

The name derives from either Ojibwe: bangii, or Cree: pahkī, both words meaning a little bit. In these colloquial uses the term may have mildly pejorative connotations, even when used by speakers to describe themselves. Bungi is unusual as a dialect in that for the Scottish immigrants and the First Nations who developed the dialect, English was often a second language.

Others, such as Brian Orvis, a Bungi-speaker from Selkirk, Manitoba, argued that Bungi is a language unto its own. He asserted that Bungee-speakers do not like to be recorded speaking the language because the First Nations values are that one should not call attention to oneself. It is because of this, he argues, that it is difficult to document Bungi, and the speakers will often deny knowledge of the language.

In addition to the being the name of a dialect, the word Bungi might have referred to a specific group of Métis of Scottish ancestry. The earliest records report that the name "Bungee" was used by the British, and especially Hudson's Bay Company employees to refer to the Saulteaux. Sometime around the turn of the 20th century, the word Bungi began to be used to refer to people of Scottish and First Nations ancestry.

The most notable particularity of Bungi is its phonology (sound system and pronunciation). Voice quality differences are also apparent. The lexicon is mostly English with borrowings from Gaelic, Cree, Ojibwa, and other languages.^{[page needed]}
