Parque provincial Moconá, Natural reserve in San Pedro Department, Argentina.

Moconá Provincial Park is a nature reserve spanning about 1,000 hectares along the Uruguay River, set within the Misiones rainforest. The park's main feature is a series of waterfalls running parallel to the river for roughly 3 kilometers.

The Moconá Reserve was created by decree 1900/1967 after landowners Juan Alberto Harriet and León Laharrague donated 999 hectares 63 ares 95 centiares containing the falls for conservation. On 4 June 1988, decree 1434/1988 established Moconá Provincial Park on that reserve, ratified by provincial law 2854 on 27 June 1991. In 1993, national law 24288 declared the Uruguay River stretch between the Yabotí and Pepirí Guazú mouths a national natural monument.

The name Moconá comes from a Guarani expression meaning "the one that swallows everything", a reference to the force of the water at the falls. The park lies opposite the Turvo State Park in Rio Grande do Sul, Brazil, which protects the same Misiones rainforest on the Brazilian bank of the Uruguay River.

The park lies in San Pedro Department, Misiones, on the Uruguay River at the Brazilian border. Access is via the road from San Pedro or from El Soberbio; the protected area is administered by the Ministry of Ecology and Renewable Natural Resources of Misiones. The falls are viewed from the Argentine bank, and the national monument status prohibits works that alter the natural setting except minor infrastructure such as walkways or docks.

The waterfalls here run parallel to the river rather than flowing straight down, a result of a geological fault in the riverbed. This unusual arrangement creates drops of varying heights along the riverbank.
