Academia Sinica (Chinese: 中央研究院, literally "Central Research Academy"; "Chinese Academy" in Latin), headquartered in the Nangang District of Taipei, is the national academy of Taiwan. It supports research activities in a wide variety of disciplines, ranging from mathematical and physical sciences, to life sciences, and to humanities and social sciences.

Academia Sinica has made great progress in recent years, according to Taiwanese scholar Chang Jui-te. An increasing number of research papers written by its faculty members, which numbered 1,150 in 2001, are appearing in international journals. Some journals published by Academia Sinica itself, such as Zoological Studies and Statistica Sinica, have received international recognition. Academia Sinica plays a major role in the field of Chinese studies. For example, the archaeological findings by researchers at the Institute of History and Philology have, in combination with written documents, led to a rewriting of ancient Chinese history, pushing back the span of Chinese history by many centuries. Academia Sinica is ranked 161st in Nature Publishing Index - 2013 Global Top 200.
