Techo International Airport is the new airport serving Phnom Penh, Cambodia. Techo International Airport opened on the 9th of September 2025, replacing Phnom Penh International Airport (formerly Pochentong International Airport).

Techo International Airport is 24 km south of the Independence Monument in Phnom Penh city centre. The airport is in Kandal province, built on former farmland and reclaimed land from a lake.

Techo International Airport has the IATA code KTI, while Phnom Penh International Airport retains the PNH IATA code.

The total land for the airport and future development area is 2,600 hectares, making it one of the biggest airports in the world by land size. The airport has a single 4,000 metre runway, with provision to build another two in the future.

A new airport was first hinted at in 2016 when plans for the current airport expansion were halted. The project was officially announced in January 2018, and construction began in 2019. The airport was officially named Techo Takhmao International Airport in December 2021.
