The Puyuma Express (Chinese: 普悠瑪號; pinyin: Pǔyōumǎ Hào) is a type of railway service on Taiwan Railway (TR) notable for using tilting trains. It began commercial service on 6 February 2013 during the Spring Festival.

Puyuma Express was commissioned by the Taiwan Railways Administration in order to upgrade the Taiwanese rail system. As the mountains of Taiwan are a barrier to coast-to-coast transportation, motor travel is prone to congestion. The high speed and capacity of the service helps to alleviate this problem. Puyuma Express also increases passenger capacity on TR. The maximum operational speed of Puyuma Express is 150 km/h (93 mph), making it the fastest service of TR. Puyuma Express belongs to the Tze-chiang limited express class of TRA services in terms of fares; however, it is a reservation-only service similarly to the Taroko Express, with no standing passengers allowed.
