Chief Henri Membertou (1507 – 18 September 1611) was the sakmow (Grand Chief) of the Mi'kmaq First Nations tribe situated near Port Royal, site of the first French settlement in Acadia, present-day Nova Scotia, Canada. Originally sakmow of the Kespukwitk district, he was appointed as Grand Chief by the sakmowk of the other six districts. Membertou claimed to have been a grown man when he first met Jacques Cartier, which makes it likely that he was born in the early years of the sixteenth century.
