Xinwu District is a rural, coastal administrative division within Taoyuan City, Taiwan. Situated in the northern part of the island, it occupies approximately 85.02 square kilometres, which accounts for nearly seven percent of Taoyuan's total land area. This makes Xinwu the sixth largest district in the city. The region is characterized by its coastal geography and is traversed by several rivers, including the Shezih, Sinwu, Foshing, Fusing, and Houhu.

The district's development has been shaped by its agricultural roots and local industry. While specific founding dates are not detailed in the available records, the area has established itself as a significant rural hub. The community is predominantly Hakka, with 88 percent of residents identifying with this ethnic group. This cultural heritage is preserved through various local institutions and historical sites that reflect the long-standing presence of Hakka families in the region.

Administratively, Xinwu comprises numerous villages such as Xinsheng, Houhu, Qinghua, and Shezi, among others. The landscape features farms, gardens, and parks that define its rural character. Notable landmarks include the Xinwu Tianhou Temple, which houses the second-tallest statue of Goddess Mazu in Taiwan and the third-tallest globally. Other key sites are the Xinwu Rice Story House and the Pacific Bicycle Museum, highlighting the district's industrial and cultural history.

Visitor appeal is driven by agricultural tourism and cultural heritage. Attractions include the Changshiang Education Farm, Fengtian Health Farm, and Jiudou Mulberry Garden. The Wangjian Hakka Rice Food Production Center offers insights into local cuisine. Educational facilities support the community with eleven elementary schools, four junior high schools, and two high schools, alongside a district library and nurseries, fostering a strong emphasis on learning and community engagement.
