The Urugua-í Provincial Park is in the north of Misiones Province, Argentina, divided between the municipalities of Comandante Andresito, San Antonio and Bernardo de Irigoyen.

[3] The park would be part of the proposed Trinational Biodiversity Corridor, which aims to provide forest connections between conservation units in Brazil, Paraguay and Argentina in the Upper Paraná ecoregion.

[4] The terrain is gently rolling in the west, with more mountainous land in the north and east where it approaches the Sierra de la Victoria, which crosses the north-southeast part of the park and forms a watershed between the Iguazu and Urugua-í rivers.

The park has a wide range of vegetation types in the valleys and mountains, including some remnants of Araucaria angustifolia in the southwest.

These include giant anteater (Myrmecophaga tridactyla), tufted capuchin (Sapajus apella), jaguar (Panthera onca), bush dog (Speothos venaticus), South American tapir (Tapirus terrestris), white-lipped peccary (Tayassu pecari) and collared peccary (Pecari tajacu).

Species include bare-faced curassow (Crax fasciolata), blue-winged macaw (Primolius maracana), blue-bellied parrot (Triclaria malachitacea), red-spectacled amazon (Amazona pretrei), purple-winged ground dove (Claravis geoffroyi), Temminck's seedeater (Sporophila falcirostris), Brazilian merganser (Mergus octosetaceus), grey-bellied hawk (Accipiter poliogaster), harpy eagle (Harpia harpyja) and canebrake groundcreeper (Clibanornis dendrocolaptoides).
