Southeast Aceh Regency () is a regency in the Aceh province of Indonesia. It is located on the island of Sumatra. In 1974, the Southeast Aceh Regency was created by being separated from the Central Aceh Regency; however in 2002 the northern part of this regency was itself split away to form the new Gayo Lues Regency. The regency now covers an area of 4,179.12 square kilometres and had a population of 179,010 at the 2010 censusBiro Pusat Statistik, Jakarta, 2011. and 220,860 at the 2020 Census;Badan Pusat Statistik, Jakarta, 2021. the official estimate as of mid 2025 was 237,910 (comprising 119,721 males and 118,189 females).Badan Pusat Statistik, Jakarta, 27 February 2026, Kabupaten Aceh Tenggara Dalam Angka 2026 (Katalog-BPS 1102001.1104) The seat of the regency government is at the town of Kutacane (in Babussalam district).

Ethnic groups The original inhabitants of Southeast Aceh Regency are the Alas people. They use the Alas language and live under the customs (adat) of those people. However, the population of the Southeast Aceh Regency has become very diverse due to migration from other regencies of Aceh and beyond. Although this Regency is part of Aceh province, the Acehnese people (an eastern coastal grouping) do not dominate this place.

Here are some other peoples other than Alas inhabiting the regency: Gayo people, the majority of whom live in Bambel district. Karo people in Babul Makmur, Lawe Sigala-Gala, Semadam, and Babussalam districts. Java Islanders (Javanese and Sundanese peoples) in Badar and Babussalam districts. Minangkabau people in Babussalam district (in the town of Kutacane). Singkil people in Bambel district. Acehnese people, mainly in Babussalam district (in the town of Kutacane).

There are other smaller ethnic groups that are still new to the Regency and do not constitute a majority population elsewhere, such as Tamiang Malays.
