East Kalimantan is the second largest Indonesian province, located on the Kalimantan region on the east of Borneo island. The resource-rich province has two major cities, Samarinda (the capital and a center for timber product) and Balikpapan (a petroleum center with oil refinery). Ever since Indonesia opened its mineral and natural resources for foreign investment in 1970s, East Kalimantan province has experienced major boost of timber, petroleum and other exotic forest products. The state-owned petroleum company Pertamina has been operating in the area since it took control oil refinery from the Royal Dutch Shell company in 1965.

The population is a mixture of people from the Indonesian archipelago with Dayaks and Kutai as indigenous ethnic groups living in rural areas. Other prominent migrant ethnic groups include Javanese, Chinese, Banjarese, Bugis and Malays, who mostly live in coastal areas.

East Kalimantan's economy heavily depends on earth resources such as oilfield exploration, natural gas, as well as coal and gold mining. Balikpapan has an oil refinery plant that was built by Dutch governance before World War II, destroyed during World War II, and rebuilt by Indonesia Governance.

Other developing economic sectors includes agriculture and tourism. East Kalimantan has several tourist destination such as Derawan Islands in Berau Regency, Kayan Mentarang National Park ini Nunukan, Crocodile Husbandry in Balikpapan, deer husbandry in Penajam, Dayak's (native Kalimantan people) Pampang Village in Samarinda and many others. Among the many obstacles to developing economic growth is lack of transportation infrastructure. Transportation depends on traditional boats connecting coastal cities and areas along main river, Mahakam River.
