Mount Hamiguitan is a mountain located in the province of Davao Oriental, Philippines. It has a height of 1,620 metres. The mountain and its vicinity has one of the most diverse wildlife populations in the country. Among the wildlife found in the area are Philippine eagles and several species of Nepenthes. Some of the latter, such as the Nepenthes peltata and Nepenthes micramphora, are endemic to the area.
