The flag of Norfolk Island is a triband consisting of green, white, and green bands charged with a green Norfolk Island pine in the centre. Adopted in 1979 when the islands gained limited self-government, it has been the flag of the Territory of Norfolk Island since 6 June of that year. The pine is native to the territory and is its official tree.
