The Posco Tower-Songdo or Northeast Asia Trade Tower (Korean: 포스코타워-송도) is a skyscraper in Songdo International City, the world's most expensive private real estate project in the Incheon Free Economic Zone, South Korea.

The building was intended to be a landmark of the Songdo International Business District which was constructed on unused land along the waterfront near Incheon.

Like One World Trade Center, the tower features a faceted glass facade that gently tapers from a square base but transitions to a triangular rooftop.

The facade is made of high-performance glazed glass with exterior shading devices which allows the structure to regulate internal temperatures.

The tower also features low-flow plumbing fixtures allowing reduced water usage by more than 20 percent compared to the average consumption rate of a typical office building.
