The Nida pronounced [ˈɲida] is a river in central Poland, a left tributary of the Vistula river, into which it flows near Nowy Korczyn). The Nida has a length of 151 kilometres (29th longest) and a basin area of 3,865 km². This includes the protected area called Nida Landscape Park.

The Nida itself is made of two smaller rivers, the White Nida and the Black Nida, which merge in the village of Brzegi (near Checiny). It is a typical lowland river, with little difference in the water level. The valley of the Nida is wide, and covered with meadows. In its narrowest spot, the river is only 6 m wide, while in its widest spot, it is 79 m wide. The depth ranges from 0,4 to 2,6 m. The Nida is one of the warmest rivers of Poland; in the summer, its temperature reaches up to 27 degrees C.

The Nida Valley is a geographic region in southern Poland, along the lower and middle Nida. It is 65 kilometres long and 2 - 6 kilometres wide. The bottom of the valley is flat and wet, with peat appearing in several locations in the former oxbow lakes. The valley is marked by numerous meadows and pastures, and its main urban centers are ancient Lesser Poland towns of Pinczow, Wislica and Nowy Korczyn.

The name Ponidzie refers to a region of Lesser Poland, which lies along the Nida, and which is much larger than the valley. It stretches from Checiny to Nowy Korczyn, with three landscape parks: Nida Landscape Park, Szaniec Landscape Park and Kozubow Landscape Park. Furthermore, there are several nature reserves, such as Przeslin, Skorocice, Krzyzanowice, Skotniki Gorne, Winiary Zagojskie, Gory Wschodnie, Grabowiec and Skowronno. In the north, the region is marked by gypsum rocks, while in the south the landscape is flat. The region has two symbols, the Adonis vernalis, and the Gothic collegiate church in Wiślica.
