The name Miramichi was first applied to places in Northumberland County in northeastern New Brunswick, Canada, but has since been transferred to distant places in both Canada and the United States. The name may have been derived from the Montagnais words "Maissimeu Assi" (meaning MicMac Land), and was perhaps introduced for use in European languages by Jacques Cartier in 1535. Many other interpretations have, however, been suggested. Miramichi may refer to:

City of Miramichi, New Brunswick, the largest city in northern New Brunswick, Canada

Miramichi Bay, an estuary located on the west coast of the Gulf of St. Lawrence at the mouth of the Miramichi River

Northwest Miramichi River, another tributary with origins near Big Bald Mountain in the Miramichi Highlands
