Ma'anyan, Dayak Maanyan or Eastern Barito Dayak people are an ethnic group of the Dayak people indigenous to Borneo. They are also considered as part of the east Barito Dusun group with the name Dusun Ma'anyan. According to J. Mallinckrodt (1927), the Dusun people group is part of the Ot Danum people cluster, although later that theory was disproved by A. B. Hudson (1967), who argues that the Ma'anyan people are a branch of the Barito family. The Ma'anyan people who are often referred to as Dayak people are also referred to as Dayak Ma'anyan. The Dayak Ma'anyan people inhabit the east side of Central Kalimantan, especially in the East Barito Regency and parts of South Barito Regency which are grouped as Ma'anyan I. The Dayak Ma'anyan people also inhabit the northern parts of South Kalimantan, especially in Tabalong Regency which refers to the Dayak Warukin people. The Dayak Balangan people or Dusun Balangan people which are found in the Balangan Regency and the Dayak Samihim people that are found in the Kotabaru Regency are grouped together with the Dayak Ma'anyan people group. The Dayak Ma'anyan people in South Kalimantan are grouped as Ma'anyan II.

South Kalimantan is a province of Indonesia. It is the smallest province in Kalimantan, the Indonesian territory of the island of Borneo. The provincial capital was Banjarmasin until 15 February 2022 when it was legally moved to Banjarbaru. The population of South Kalimantan was recorded at just over 3.625 million people at the 2010 Census, and at 4.07 million at the 2020 Census. The official estimate as at mid 2023 was 4,221,929. One of the five Indonesian provinces in Kalimantan, it is bordered by the Makassar Strait in the east, Central Kalimantan in the west and north, the Java Sea in the south, and East Kalimantan in the northeast. The province also includes the island of Pulau Laut, located off the eastern coast of Kalimantan, as well as other smaller offshore islands. The province is divided into 11 regencies and 2 cities. South Kalimantan is the traditional homeland of the Banjar people, although some parts of East Kalimantan and Central Kalimantan are also included in this criterion. Nevertheless, South Kalimantan, especially the former capital city Banjarmasin has always been the cultural capital of Banjarese culture. Many Banjarese have migrated to other parts of Indonesia, as well as neighbouring countries such as Singapore and Malaysia. In addition, other ethnic groups also inhabit the province, such as several groups of the Dayaks, who mostly live in the interior part of the province, as well as the Javanese, who mostly migrated from Java due to the Transmigration program which dated from the Dutch colonial era. It is one of the provinces in Indonesia that has a larger population than Mongolia.
