East Kalimantan (Indonesian: Kalimantan Timur abbrv. Kaltim) 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).

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.
