Lhokseumawe (,, ), is the second largest city (by population, after Banda Aceh) in Aceh province, Indonesia, having recently overtaken Langsa. The city covers a land area of 181.06 square kilometres, and had a population of 171,163 at the 2010 census and 188,713 at the 2020 census; the official estimate as of mid 2025 was 200,876 (comprising 98,717 males and 99,988 females in 2024). The city is a key regional centre important for the economy of Aceh.
The name Lhokseumawe comes from the words lhok and seumawe. Lhok means "deep", "bay", and "ocean trenches", and Lhokseumawe means the swirling water in the sea along the offshore of Banda Sakti and its surroundings. The city was formerly part of North Aceh Regency, from which it was separated to form an independent city on 21 June 2001. The area is linked to the emergence of the kingdom of Samudera Pasai around the 13th century, which later came under the sovereignty of Sultanate of Aceh in 1511.
Map of Aceh Sultanate during the reign of Sultan Iskandar Muda The Sultanate of Aceh was established by Sultan Ali Mughayatsyah in 1511. Later, during its golden era, in the 17th century, its territory and political influence expanded as far as Satun in southern Thailand, Johor in Malay Peninsula, and Siak in what is today the province of Riau. As was the case with most non-Javan pre-colonial states, Acehnese power expanded outward by sea rather than inland. As it expanded down the Sumatran coast, its main competitors were Johor and Portuguese Malacca on the other side of the Straits of Malacca. It was this seaborne trade focus that saw Aceh rely on rice imports from north Java rather than develop self sufficiency in rice production. After the Portuguese occupation of Malacca in 1511, many Islamic traders passing the Malacca Straits shifted their trade to Banda Aceh and increased the Acehnese rulers' wealth. During the reign of Sultan Iskandar Muda in the 17th century, Aceh's influence extended to most of Sumatra and the Malay Peninsula. Aceh allied itself with the Ottoman Empire and the Dutch East India Company in their struggle against the Portuguese and the Johor Sultanate. Acehnese military power waned gradually thereafter, and Aceh ceded its territory of Pariaman in West Sumatra to the Dutch in the 18th century.
