Lennox Island is a Mi'kmaq First Nation on Prince Edward Island, Canada, with its headquarters in Lennox Island, northeast of Tyne Valley. The band consists of a single reserve occupying all of Lennox Island.
The Lennox Island First Nation was originally known as "L'nui Minegoo" or the Indian/People's Island, and later known as the Lennox Island Reserve or the Lennox Island Band. It was named after Charles Lennox, Duke of Richmond, by Samuel Holland; surveyor. It also included the reserves that now comprise the Abegweit First Nation. Original permanent inhabitants included Chief Francis Francis who resided there after the Mi'kmaq were displaced from Cortin Island. The Saint Ann Mission was later established on the island.
