The Phi Pan Nam Range, also Pee Pan Nam, (Thai: ทิวเขาผีปันน้ำ) is a 400 km (249 mi) long system of mountain ranges in the eastern half of the Thai highlands. It is mostly in Thailand, although a small section in the northeast is within Sainyabuli and Bokeo Provinces, Laos.
In Thailand the range extends mainly across Chiang Rai, Phayao, Lampang, Phrae, Nan, Uttaradit and Sukhothai Provinces, reaching Tak Province at its southwestern end. The population density of the area is relatively low. Only two sizable towns, Phayao and Phrae, are within the area of the mountain system and both have fewer than 20,000 inhabitants each. Larger towns, like Chiang Rai and Uttaradit, are near the limits of the Phi Pan Nam Range, in the north and in the south respectively.
Phahonyothin Road, part of the AH2 Highway system, crosses the Phi Pan Nam Range area from north to south, between Tak and Chiang Rai. There are two railway tunnels of the Northern Line across the Phi Pan Nam mountains. Both are on the south side of the range: the 130.2 m Huai Mae Lan Tunnel in Phrae Province and the 362.4 m Khao Phlueng Tunnel in Uttaradit and Phrae Provinces.
