Taipei Basin

The Taipei Basin (traditional Chinese: 臺北盆地; simplified Chinese: 台北盆地; pinyin: Táiběi Péndì) is a geographic region in northern Taiwan. It is the largest basin in Taiwan. The basin is bounded by the Yangmingshan to the north, the Linkou Plateau to the west, and the Ridge of Xueshan Range to the southeast. The shape of the basin is close to a triangle. The three vertices are Nangang, Huilong of Xinzhuang, and Guandu of Beitou.

The main rivers in the Taipei Basin include the Tamsui, Keelung, Dahan and Xindian.

In the prehistoric era, the Taipei Basin was home to Ketagalan tribes. Han Chinese did not settle in the region until the 18th century. Today, Taipei Basin is within the boundaries of Taipei City and New Taipei City and is the largest metropolitan area in Taiwan.
