National Freeway 2 (Chinese: 國道二號) is a connector freeway in Taiwan that traverses the special municipalities of Taoyuan City and New Taipei City. The freeway begins at Taiwan Taoyuan International Airport in Dayuan District, Taoyuan City, traveling in a northwest–southeast direction along northern Taoyuan City and ends in Yingge at the junction with National Freeway 3. It is 20.4 km (12.7 mi) long.

The freeway was initially signed as National Freeway 1A (Chinese: 國道一甲) from 1980 to 1997 before the highway was extended to its current eastern terminus in Yingge. The initial segment of the freeway, between Taipei Taoyuan International Airport and National Freeway 1 is commonly known as Airport Connector (Chinese: 機場支線), while the segment between National Freeway 1 and National Freeway 3 is a part of the Taoyuan Ring Road (Chinese: 桃園環線).

The airport is an important connector that links the international airport and Taoyuan HSR station with National Freeways 1 and 3. Like all east–west freeways in Taiwan, there are no tolls traveling along the entire freeway.
