Yonghe District (Chinese: 永和區; pinyin: Yǒnghé Qū; Pe̍h-ōe-jī: Éng-hô-khu) is an inner city district in the southern part of New Taipei, Taiwan. Yonghe District is the smallest district in New Taipei City.
On 1 January 1979, Yonghe was established as county-controlled city of Taipei County. With the changing of Taipei County to the special municipality of New Taipei City on 25 December 2010, Yonghe City was changed to Yonghe District. The Xindian River forms a natural boundary between Yonghe and Taipei City to the north and east, although three bridges connect the two areas. To the south and west lies Zhonghe District, which shares some administration and facilities with Yonghe.
Before the city was merged with New Taipei and became a district, it had the highest population density in Taiwan and second in the World (after Manila in the Philippines), with over 41,300 people per square km.
