Whangarei District is a territorial authority district in the Northland Region of New Zealand that is governed by the Whangarei District Council. The district is made up in area largely by rural land, and includes a fifth of the Northland Region. It extends southwards to the southern end of Bream Bay, northwards to Whangaruru and almost to the Bay of Islands, and westwards up the Mangakahia River valley past Pakotai and almost to Waipoua Forest. It includes the Hen and Chicken Islands and the Poor Knights Islands.
