Tuoba Shiyijian (Chinese: 拓跋什翼犍; pinyin: Tuòbá Shíyìjiàn; 320–376) was the last prince of the Tuoba Dai and ruled from 338 to 376 when Dai was conquered by the Former Qin. He was the son of Tuoba Yulü and the younger brother of Tuoba Yihuai, whom he succeeded in 338. In 340 he moved the capital to Shengle (盛樂) (near modern Horinger County, Inner Mongolia). His grandson Tuoba Gui founded the Northern Wei dynasty.
