The Pulangi River (Cebuano pronunciation IPA [puˈlaŋi]), also spelled Pulangui, is the longest river in Bukidnon. It is one of the major tributaries of the Rio Grande de Mindanao, an extensive river system in Mindanao, Philippines. It has a length of 320 kilometers and traverses through majority of the cities and municipalities of Bukidnon from its source in Barangay Kalabugao, Impasugong, Bukidnon.

The name of the river could have come from the Manobo term “Empamulangi”, meaning "center of the island", referring to the location of the river within the island of Mindanao.

Pulangi has one reservoir type power plant, the Pulangi IV Hydroelectric Plant and watershed. The Pulangi IV Hydroelectric Plant has a capacity of 255 megawatts and provides for 25% of Mindanao's power needs. It is owned and operated by the National Power Corporation(NAPOCOR). The reservoir and dam is also the main water source for the province of Bukidnon, both for drinking water and for irrigation through the National Irrigation Administration (NIA).

The Pulangi IV Hydroelectric Plant watershed (also known as the Upper Pulangi Watershed) is the second largest watershed in the Philippines, covering an area of around 1.8 Million hectares. It has ten catchments and covers the cities and municipalities of Impasugong, Cabanglasan, San Fernando, Lantapan, Maramag, Quezon, Valencia City, and Malaybalay City.
