Kunming Changshui International Airport (IATA: KMG, ICAO: ZPPP) is an international airport serving Kunming, the capital of Southwestern China's Yunnan province. The airport is located 24.5 km (15.2 mi) northeast of the city center in a graded mountainous area about 2,100 m (6,900 ft) above sea level. The airport opened at 08:00 (UTC+8) on 28 June 2012, replacing the old Kunming Wujiaba International Airport, which was later demolished. As a gateway to Southeast and South Asia, Changshui Airport is a hub for China Eastern Airlines, Kunming Airlines, Lucky Air, Sichuan Airlines and Ruili Airlines.

The new airport has two runways (versus the single runway at Wujiaba), and handled over 47,000,000 passengers in 2024, making it the 47th busiest airport in the world and 4th busiest airport in China by passenger traffic.

In 2025, the airport's passenger throughput reached 49.7057 million, ranking tenth among airports in China.

The main terminal was designed by architectural firm SOM with engineering firm Arup.

Construction began in 2009. At the time, the facility was reported to be named the Zheng He International Airport, named after Zheng He, a Chinese mariner, explorer, and diplomat.

The very short construction time was marred by two separate incidents. The first occurred on January 3, 2010, when seven construction workers died as an incomplete overpass collapsed. On June 28, 2011, 11 workers were injured when a tunnel that was under construction collapsed.

Construction of the airport's main terminal was completed by July 2011.

The main 548,300 m² (5,901,852 sq ft) terminal of Changshui International Airport is the second largest terminal building in China. The terminal has 66 gates with jet bridges. A total of 88 gates are available.
