La formation d'Ischigualasto est une formation géologique du Trias supérieur (Carnien-Norien) située dans le nord-ouest de l'Argentine, dans le parc provincial d'Ischigualasto. Elle a livré une faune fossile abondante en vertébrés terrestres, parmi lesquels les plus anciennes espèces connues de dinosaures. Elle appartient au groupe d'Agua de la Peña, et vient au-dessus de la formation de Los Rastros.

The Ischigualasto Formation is a Late Triassic formation and Lagerstätte in the Ischigualasto-Villa Unión Basin of the southwestern La Rioja Province and northeastern San Juan Province in northwestern Argentina. The formation dates to the Carnian and Norian ages and ranges between 231.7 and 225 Ma, based on ash bed dating. The up to 900 metres (3,000 ft) thick formation is part of the , overlies Los Rastros Formation and is overlain by Los Colorados Formation. The formation is subdivided into four members, from old to young; La Peña, Cancha de Bochas, Valle de la Luna and Quebrada de la Sal. The sandstones, mudstones, conglomerates and tuffs of the formation were deposited in a humid alluvial to fluvial floodplain environment, characterized by strongly seasonal rainfall. The Ischigualasto Formation is an important paleontological unit and considered a Lagerstätte, as it preserves several genera of early dinosaurs, other archosaurs, synapsids, and temnospondyls of the Late Triassic. Coprolites and fossil wood also have been found in the formation. The formation crops out in the in 1967 established Ischigualasto Provincial Park, which was designated a UNESCO World Heritage Site in 2000.
