Shanghai has one of the oldest Muslim communities among China's major cities, built on a long history of trade and internal migration from majority-Muslim provinces. The historic heart of this community is Xiaotaoyuan Mosque, located in Huangpu district right near the old city and Yu Garden — Shanghai's largest and oldest active mosque. First built in 1917, it was completely rebuilt in 1925 and finished in its current form two years later, in an architectural style blending traditional West Asian Islamic design with local Chinese elements, with a green facade and a distinctive minaret visible from the surrounding streets. The mosque has been registered as a heritage architectural site by the Shanghai municipal government since 1994.

Around the mosque and along Fuxing East Road, most of the old city's halal restaurants and shops are concentrated, making this area an ideal starting point for any halal food plan. Shanghai's halal food scene is shaped by two distinct main traditions: Chinese Hui Muslim cuisine from eastern China, closer to traditional Chinese cooking with halal adjustments, and Xinjiang Uyghur cuisine from northwestern China, found spread across various commercial districts throughout the city, not just around the mosque. Notable names include Salaam New Idea Muslim Restaurant, Efes Turkish Restaurant, Uighur Restaurant, and Islamic Restaurant, plus a branch of the 1001 Nights chain found in several Chinese cities, serving a mix of authentic Chinese, Uyghur, Turkish, and Indian food.

Besides Xiaotaoyuan, there are other smaller mosques scattered across Shanghai, including Songjiang Mosque and Huxi Mosque on the city's west side, plus one in the modern Pudong area — useful if you're staying far from the old city or planning a full day in Pudong and want to pray without heading back downtown.

For practical planning, download Baidu Maps or Amap and search "清真" (qīngzhēn), the official mark for halal food in China, and learn to visually recognize it. Never assume a dish that looks vegetarian or chicken-based is automatically halal — chicken and vegetable broths in traditional Chinese cooking often contain pork-derived ingredients, so asking directly is necessary at any restaurant without a clear "清真" sign. Carry a translated card explaining your dietary needs, which makes communication easier at restaurants where staff don't speak English. Finally, Xiaotaoyuan Mosque welcomes traveling worshippers and visitors, and is worth an architectural visit even for non-worshippers — a rare window into the history of Islam in eastern China, which stretches back centuries before any of this.
