The Luang Prabang Range (Thai: ทิวเขาหลวงพระบาง,  [tʰīw kʰǎw lǔaŋ pʰráʔ.bāːŋ]), named after Luang Prabang, is a mountain range straddling northwestern Laos and Northern Thailand.

Most of the range is located in Sainyabuli Province (Laos), as well as Nan and Uttaradit Provinces (Thailand), with small parts in Phitsanulok and Loei Provinces.
Several rivers such as the Nan, Pua and Wa river, have their source in this range.
Phu Fa waterfall, the biggest and the tallest waterfall in Nan Province, is also located in these mountains.
This range is part of the Luang Prabang montane rain forests ecoregion.

Geologically its composition is similar to that of the parallel Khun Tan Range and the Phi Pan Nam Range, both located further west.
