Auyán-tepui ((:auˌʝanteˈpui)), also spelled Ayan,〔Barnett, A., R. Shapley, P. Benjamin, E. Henry & M. McGarrell (2002). ''Cotinga'' 18: 19–36.〕 is a tepui in Bolívar state, Venezuela.〔Huber, O. (1995). Geographical and physical features. In: P.E. Berry, B.K. Holst & K. Yatskievych (eds.) ''Flora of the Venezuelan Guayana. Volume 1. Introduction.'' Missouri Botanical Garden Press, St. Louis. pp. 1–61.〕 It is the most visited and one of the largest (but not the highest) tepuis in the Guiana Highlands, with a summit area of and an estimated slope area of .〔 The uneven, heart-shaped summit plateau of Auyán-tepui is heavily inclined, rising from around in the northwest to a maximum of in the southeast.〔 It is incised from the north by a vast valley, the Cañón del Diablo (Devil's Canyon), formed by the Churún River. The larger western portion of the plateau is partially forested, whereas the eastern part comprises mostly bare rock with only patchy vegetation cover.〔 The mountain hosts a number of extensive cave systems.〔Piccini, L.

Solution weathering rate and origin of karst landforms and caves in the quartzite of Auyan-tepui (Gran Sabana, Venezuela). ''Geomorphology'' 106(1–2): 15–25. 〕 Auyán-tepui gives its name to the Auyán Massif, which also includes the tiny peaks of Cerro El Sol and Cerro La Luna to the north, and the satellite mountain of Uaipán-tepui to the south. The massif has a total summit area of roughly and an estimated slope area of .〔 It is situated entirely within the bounds of Canaima National Park.〔 Torres, I.N. & D.D. Martín (November 2007). Mejorando Nuestra Herencia.〕 Auyán-tepui means "Devil's House" in the local Pemón language.〔 Angel Falls, the tallest waterfall in the world, drops from a cleft near the summit. The falls are high, with an uninterrupted descent of 〔 Brewer-Carías, C. (2010). (Tras la huella: del Salto Angel ). ''Río Verde'' 2: 61–77.〕 — a drop nineteen times higher than that of Niagara Falls. Auyán-tepui achieved international fame in 1933 when Angel Falls was accidentally discovered by Jimmie Angel, a bush pilot searching for gold ore. Attempting to land on the heart-shaped mesa in 1937, Angel crashed his small Flamingo plane on top of Auyán-tepui and was forced to hike down the gradually sloping backside, a trip that took him and his crew 11 days to complete; he was immortalised when the waterfall was named after him.〔Angel, K. (2001) (2009, 2010 ). Alexander von Humboldt International Conference 2001, Humboldt State University, Arcata, California.〕 Around 25 species of amphibians and reptiles are known from the summit plateau of Auyán-tepui,〔Myers, C.W. & M.A. Donnelly (March 2008).
