The Paraná flooded savanna (NT0908) is an ecoregion that borders the southern Paraná River in Argentina. It has largely been converted to agriculture or occupied by urban development, but scattered patches of the original habitat remain along the river.

The Paraná flooded savanna ecoregion has an area of 3,885,000 hectares (9,600,000 acres). It extends along the Paraná River valley from Resistencia, Chaco, south to Buenos Aires. It includes the middle and lower Paraná floodplains, and those of the Paraguay River, a major tributary of the Paraná. In the south it includes the Paraná delta and the basin of the Río de la Plata. The ecoregion consists of a strip of land that runs through the Humid Chaco ecoregion in the north. Further south it runs through the Espinal ecoregion and then the Humid Pampas ecoregion before reaching the Río de la Plata estuary.

The region contains wide coastal lowlands, and low islands subject to flooding between the channels of the rivers. The large bodies of water give high humidity and temper the daily and seasonal temperature extremes. The Köppen climate classification is "Cfa": warm temperate, fully humid, hot summer. At a sample location at coordinates 31°15′S 59°45′W / 31.25°S 59.75°W / -31.25; -59.75 average annual temperature is 19 °C (66 °F). It is coolest in July with a mean temperature of 12.4 °C (54.3 °F) and warmest in January with a mean temperature of 25.4 °C (77.7 °F). Total rainfall averages about 1,100 millimetres (43 in). Monthly rainfall ranges from 30.1 millimetres (1.19 in) in July to 137.4 millimetres (5.41 in) in March.
