The flag of Labrador, while unofficial, is used to represent the mainland part of the Canadian province of Newfoundland and Labrador as distinct from the island of Newfoundland. It was designed in 1973 by Michael S. Martin. The flag has been influential in Labrador; its colours are mirrored in the flag of Nunatsiavut, and its spruce twig was adopted for use on the Franco-Terreneuvien flag.
The top white bar represents the snow which colours the culture and lifestyle of Labradorians like no other element. The bottom blue bar represents the waters of Labrador which serve as the highway and sustainer of the people of Labrador. The centre green bar represents the nurturing land. It is thinner than the other two, as the northern climes of Labrador have short summers.
The twig is in two year-growths to represent the past and future of Labrador. The shorter growth of the inner twigs represents the hardships of the past, while the outer twigs are longer as a representation of the hope Labradorians have for the future. The three branches represent the three founding nations of Labrador; the Innu, the Inuit, and the white settler. The three branches emerging from a single stalk represents the unity of the distinct peoples in the brotherhood of mankind.
