The Northern Province (Tamil: வட மாகாணம் Vaṭa Mākāṇam; Sinhalese: උතුරු පළාත Uturu Paḷāta) is one of the nine provinces of Sri Lanka, the first level administrative division of the country. The provinces have existed since the 19th century but did not have any legal status until 1987 when the 13th Amendment to the Constitution of Sri Lanka established provincial councils. Between 1988 and 2006 the province was temporarily merged with the Eastern Province to form the North Eastern Province. The capital of the province is Jaffna. The majority of the Sri Lankan Civil War was played out in this province.

Parts of present-day Northern Province were part of the pre-colonial Jaffna kingdom. Other parts were ruled by Vanniar Chieftains who paid tribute to the Jaffna kingdom. The province then came under Portuguese, Dutch and British control. In 1815 the British gained control of the entire island of Ceylon. They divided the island into three ethnic based administrative structures: Low Country Sinhalese, Kandyan Sinhalese and Tamil. The Northern Province was part of the Tamil administration. In 1833, in accordance with the recommendations of the Colebrooke-Cameron Commission, the ethnic based administrative structures were unified into a single administration divided into five geographic provinces. The districts of Jaffna, Mannar, Nuvarakalaviya (present day Anuradhapura District) and Vanni formed the new Northern Province. Nuvarakalaviya was transferred to the newly created North Central Province in 1873.
