The Xibe (Sibe; Chinese, 錫伯 Xibo) are a Chinese ethnic group living mostly in northeast China and Xinjiang. They form one of the 56 ethnic groups officially recognized by the People's Republic of China.

The Xibe in northeast China speak Chinese as mother tongue.

In Xinjiang, descendants of a Qing dynasty military garrison preserve their language, which is very close to Manchu. They use the Xibe script, a slightly revised Manchu script.

The Xibe believe that they are descendants of the Xianbei.
