Metepenagiag (pronounced MET-EHH-PE-NAH-GHEE-AH), also known as Red Bank is a Mi'kmaq First Nation band government in New Brunswick, Canada on the other side of the Miramichi river from Sunny Corner.

For thousands of years Mi’kmaq communities along New Brunswick’s northeastern shore lived near tidal estuaries where tidal saltwater flows inland and creates an ecosystem for "anadromous fish species such as salmon, sturgeon, gaspereau or alewife, striped bass, and eel, that seasonally move up the estuaries in large numbers."

The Augustine Mound has similarities to the elaborate burial rites of the Adena culture of the Ohio Valley and contained materials that were not local including copper from Lake Superior area.

Turnbull argues that the Red Bank people were part of a broad Northeastern pre-contact trade network.

In 1982, the nearby Oxbow archaeological site, located within the reserve land of the Metepenagiag Mi’kmaq Nation on an oxbow bend of the Southwest Miramichi River,[8] was also designated a National Historic Site of Canada for its role as "witness and record of 3000 years of continuous Mi’kmaq use of the site".The Oxbow "contains evidence of 3,000 years of Mi’kmaq history (from 1,000 BC to the present) on the north bank of the Little Southwest Miramichi River at the head of tide.

Annual flooding of the river bank has created a well-stratified site in which the cultural development through time is preserved in multiple layers of sediment.
