Taipei American School (TAS; Chinese: 臺北美國學校; pinyin: Táiběi Měiguó Xuéxiào; Pe̍h-ōe-jī: Tâi-pak Bí-kok Ha̍k-hāu; abbreviation TAS) is a non-profit private international school with an American-based curriculum located in Tianmu, Shilin District, Taipei, Taiwan.

Upon termination of diplomatic relations between the United States and the ROC in 1979, TAS was reorganized into a private international school.

The first meeting of Taipei American School took place on September 26, 1949, in the basement of Presbyterian Theological Seminary at Zhongshan North Road, with eight students.

By 1951, the influx of missionaries and business people escaping from the communist victory in mainland China caused enrollment to grow to 120 students.

By 1952, TAS was forced to relocate to Nong'an East Road to provide space for the growing student population In 1953, the U.S. Military Assistance Advisory Group was established in Taiwan.

Bordered on two sides by a river, the Shilin campus was prone to flooding during the typhoons experienced on Taiwan when the protective dikes were breached.

Within a few years, enrollment started to increase again as overseas Chinese with foreign passports arrived in Taiwan searching for American educational facilities for their children.

As part of this celebration, TAS published a book documenting the history of the school: "Ties That Bind", authored by Richard Vuylsteke.

In September 2010, TAS broke ground for the construction of three new buildings on its current campus: the new upper school building featuring science and technology classrooms with research and robotics laboratories, the Liu Lim Arts Center, and another gymnasium with covered and outdoor tennis courts.

The independently operated Taipei Youth Program Association (TYPA) is located at TAS and uses the campus facilities.

Board members are elected by the Taipei American School Association, which consists of all parents or guardians of children attending TAS.

Almost 100 percent of TAS graduates continue their education at a college or university, the vast majority in the United States.

Previously known as Paws, the Blue & Gold newspaper has won awards from the National Scholastic Press Association (NSPA).
