Lóngyuān (龍渊) is the former name of Lóngquán (龍泉), a town along the Ou river in Zhejiang province, China, known for its sword making.

The founder of the Tang dynasty, Emperor Gaozu, banned the use of the character yuān as it was part of his personal name and thus it came to be known as Lóngquán.

Yuān means a deep pool, or "deep/profound" in meaning. Before this event, swords from lóngquán could also be called yuān jiàn (渊劍); "deep well sword".
