Alexander Denny (July 26, 1940 – 2004), otherwise known as Kji-keptin (Grand Captain) Alex Denny of the Mi'kmaq Grand Council, both a founding member and two-term president (1974–1976 and 1992–1995) of the UNSI (Union of Nova Scotia Indians), was most prominently known for the role he played in the ongoing battle for recognition of Mi'kmaq treaties and Aboriginal rights. Born to the Eskasoni First Nation and raised by two elders in the community, Denny was taught the importance of Mi'kmaq treaties from a young age. His passion for and knowledge of his community ultimately led Denny to be credited with attaining linguistic and political rights for the Mi'kmaq Nation at an international level. Additionally, It was Denny and the UNSI that organized the very first Treaty Day.
