Air Terjun Tumburano, Three-tiered waterfall in Konawe Archipelago Regency, Southeast Sulawesi, Indonesia.

Air Terjun Tumburano is a waterfall on Wowoni Island in Southeast Sulawesi, estimated at about 120 metres high with three large tiers and several smaller steps. Its water slides down a giant brown sedimentary rock face shaped like the roof of a traditional house, with a hollow behind it that looks like a hanging cave. The flow forms a large pool and mist below.

The waterfall lies in Lansilowo Village, North Wawonii District, within Konawe Archipelago Regency, a regency created in 2013 when it was separated from Konawe Regency in Southeast Sulawesi. The name Tumburano means "falling water" in the local language, a toponym recorded for this cascade on Wowoni Island.

The name Tumburano means "falling water" or "place where water falls" in the local language, describing the cascade itself. The waterfall is the tallest and largest in North Wawonii District, and its flow swells in the rainy season and shrinks in the dry season, when the water turns clearer.

Access begins with a three-hour ferry crossing from Kendari to Lansilowo Village, followed by seven kilometres by motorcycle or on foot. The final stretch is rough and uneven, so wear sturdy footwear and carry enough water. In the rainy season the flow is heavy and the spray soaks the rock; in the dry season it thins and the water turns clearer.

The rock face is a dissolved limestone formation millions of years old, hollow at the back so it resembles a hanging cave. Its shape is compared to the roof of a traditional house, and the falling water forms a large pool and mist below. The site is used for outdoor activities such as rappelling down the cliff.
