Tjilik Riwut Airport is the primary commercial airport serving Palangkaraya, the capital of Central Kalimantan province on the island of Borneo, Indonesia. It is named after Tjilik Riwut, a prominent local governor and independence fighter who played a significant role in the region's history. The airport handles domestic flights connecting Palangkaraya to major Indonesian cities including Jakarta, Surabaya, and Balikpapan. It serves as an important transportation hub for a province largely covered by rainforest and river systems, where air travel is often the most practical means of reaching the capital. In recent years the airport has undergone infrastructure improvements to accommodate growing passenger traffic, reflecting Central Kalimantan's economic development linked to palm oil, mining, and its proximity to Indonesia's planned new capital city, Nusantara.
