List of tallest buildings in Tainan

Tainan is a city located in southern Taiwan, with a population of 1,874,917 as of 2020. It is the second largest city in southern Taiwan, after Kaohsiung, and the fifth largest metropolitan area in the country. Despite being the oldest city in Taiwan, Tainan has relatively few tall buildings, relative to other major cities in Taiwan. The tallest building in the city is the 140 m (459 ft), 38-story Shangri-La's Far Eastern Plaza Hotel Tainan, which has been the city's tallest building for over 30 years since it was built in 1993.

The first high-rises in the city appeared towards the late 1980s and early 1990s. Tainan's skyline is recent with most tall buildings being built after 2000. Commercial high-rises are relatively uncommon, with the tallest being the Fubon Financial Center, built in 2002. Instead, most of the city's high-rises are residential, and there have been a growing number of them built starting from the 2010s. With only four buildings above 100 m (328 ft) in 2010, this boom has led to the city having 13 of them as of 2026. However, none of them reach over 150 meters (492 feet).

The skyline of the city is quite disperse, with no particular area having the largest concentration of tall buildings. The city's tallest buildings are located in three central districts of Anping, West Central District (also known as Zhongxi District) and East District. The tallest residential high-rises that were built recently are mainly located in Anping and West Central District. Further projects under construction will add taller buildings to Annan and Shanhua districts above 100 m (328 ft).
