Yumbilla Falls is a waterfall located near the town of Cuispes, in the northern Peruvian region of Amazonas. It is considered the world's fifth tallest waterfall, becoming internationally known since late 2007 due to a geographical survey conducted by the Geographical Institute of Peru (IGN).

Yumbilla is 895.5 m (2,938 ft) high, with the top located 2,723.6 m (8,936 ft) above sea level and the base at 1,828.1 m (5,998 ft). The height was measured with the help of laser instruments by a geographical survey of the National Geographic Institute of Peru (IGN) in 2007. This area is part of the Eastern Peruvian Andes, also known as Cordillera Oriental, more precisely, part of a mountain massif called Cerro Panhuayco.

Yumbilla is considered a tiered type waterfall, since it comprises four or five sections or drops. The stream is reported to come from a cave named "Caverna San Francisco".

The reported mean temperature in the area is 22 °C, with a rainy season from December to April.

The area around the waterfall is covered with montane forest vegetation. Bromeliads, orchids (Epidendrum secundum, Fernandezia ionanthera, Oncidium scansor), palms (Ceroxylon parvifrons), Andean alders (Alnus acuminata) and tree ferns (Cyathea spp.) are commonly found in the area.

Animals reported in the area include birds like the Andean cock-of-the-rock and the marvellous spatuletail hummingbird; and mammals like the spectacled bear and the yellow-tailed woolly monkey.
