Sinhua District, alternatively spelled Xinhua, is a suburban district in central Tainan, Taiwan.

Tainan, officially Tainan City, is a special municipality in southern Taiwan facing the Taiwan Strait on its western coast. Tainan is the oldest city on the island and commonly called the "prefectural capital" for its over 260 years of history as the capital of Taiwan under the Dutch rule, the Kingdom of Tungning and later Qing dynasty rule until 1887. Tainan's complex history of comebacks, redefinitions and renewals inspired its popular nickname "the Phoenix City". Tainan is classified as a "Sufficiency"-level global city by the Globalization and World Cities Research Network.
