Mount Damper Falls is a 74-metre waterfall in the Taranaki region of New Zealand's North Island, dropping on Mount Damper Stream, a tributary of the Tongapōrutu River.

At that height, it ranks among the tallest waterfalls in the North Island, behind Wairere, Ananui, and Waitakere Falls.

The falls are reached via a short walking track beginning near the intersection of Okau and Mangapapa Roads off State Highway 43, roughly 59 km north of New Plymouth.

The track crosses privately owned farmland before entering conservation land managed by the Department of Conservation. Access is closed annually from 1 August to 31 October during the lambing season.

The falls form part of the heritage trail network along the Forgotten World Highway and lie near the historic Tihi-Manuka trail, once used by local Māori as a main route between the Taumaranui area and the north Taranaki coast.
