The Subangdaku River is the largest river in Southern Leyte, Philippines. It drains into the Sogod Bay at the municipality of Sogod. The river's name means "big river" or "wide river" in Cebuano.
For years, following the flooding of the river, it created an issue over the province. It has been quarried and re-channeled which caused the incidents. After many attempts, the issue remained unsolved.
