The Academia Sinica Institute of Astronomy and Astrophysics (ASIAA or IAA) is an affiliated research institute of Academia Sinica in Taipei.

ASIAA is currently located in the Astronomy and Mathematics Building at the National Taiwan University in Taipei, Taiwan and also has a field office in Hilo, Hawaii.

ASIAA was officially established on June 1, 2010, with Paul Ho being the first director.

The research areas of ASIAA range from the Solar System to star formation to galaxies and cosmology. ASIAA has either led or co-led the construction and operation of several telescopes, including the AMiBA Telescope to study the cosmic microwave background radiation (also known as "Lee Array"), the Taiwanese-American Occultation Survey, the Submillimeter Array and many other research projects.

ASIAA is involved in several research projects, including:

• Taiwanese–American Occultation Survey (TAOS)
• Transneptunian Automated Occultation Survey (TAOS II)
• Yuan Tseh Lee Array for Microwave Background Anisotropy (AMiBA)
• Theoretical Institute for Advanced Research in Astrophysics (TIARA)
• Hyper Suprime-Cam (HSC) Survey
• Atacama Large Millimeter/submillimeter Array (ALMA)
