North Aceh Regency

North Aceh Regency (Indonesian: Kabupaten Aceh Utara) is a regency in Aceh province of Indonesia. It is located on the island of Sumatra. The regency covers a land area of 2,705.26 square kilometres and had a population of 534,085 at the 2010 census and 602,793 at the 2020 Census; the official estimate as of mid 2025 was 647,619 (comprising 322,625 males and 324,994 females).

The administrative centre is now at the town of Lhoksukon; this followed the splitting off of the western districts from the regency to form (by Law No. 48 of 1999) a separate Bireuen Regency on 4 October 1999, and then the creation (by Law No. 2 of 2001) of the independent city of Lhokseumawe out of what was formerly the capital, which was cut out of the regency on 21 June 2001.
