The Luang Prabang Range (Thai: ทิวเขาหลวงพระบาง, pronounced [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.

The Luang Prabang mountains are the easternmost range of the Thai highlands. The range runs roughly in a North/South direction between the Mekong and the Nan River. Its northern end begins in the area of Hongsa District, a stretch in Laos near Luang Prabang where the Mekong River flows from west to east; its southern end is about 260 km further south, at the western end of Loei Province in Thailand where the Phetchabun Mountains begin. The highest point of the range is 2,120 m high Phu Soi Dao. Other high peaks of the Luang Prabang Range are 2,079 m high Phu Khe, 1,980 m high Doi Phu Kha, 1,837 m high Doi Phu Wae and 1,745 m high Doi Phi Pan Nam; Phu Khe is one of the ultra prominent peaks of Southeast Asia. Many of the important peaks are located at the border.
