Aji Pangeran Tumenggung Pranoto Airport (IATA: AAP, ICAO: WALS), also known as APT Pranoto Airport or Samarinda Airport, is an airport serving Samarinda, the provincial capital city of East Kalimantan, Indonesia. It is in the village of Sungai Siring at the North Samarinda district, close to the border with Muara Badak. The airport is also colloquially known as Sungai Siring Airport, to distinguish it from its predecessor, the now-closed Temindung Airport. The airport is named after Aji Pangeran Tumenggung Pranoto, the first governor of East Kalimantan who was in office from 1957 to 1961.

The airport started commercial operation on 24 May 2018, replacing the Temindung Airport. The airport is operated by UPBU APT Pranoto Samarinda, under the Ministry of Transportation. In 2022, the Indonesian Ministry of Transportation planned to partially sell the airport stake to foreign corporation and Astra Infra.

Having been in commercial operation since 2018, Samarinda Airport is an important Australian passenger gateway for East Borneo's wildlife, and an important contributor to Samarinda's economy, which is lying at BIMP-EAGA and bordering with the new capital of Indonesia. Strategically located at the heart of East Borneo and its proximity to the new capital of Indonesia, the transport authority is enhancing the airport's status as East Borneo's primary international hub airport.

In 2019, Samarinda Airport handled 1.1 million passengers and according to Indonesian government, the airport will reach its maximum terminal capacity (1.5 million passengers) if no extra terminal is added.
