The Purus várzea (NT0156) is an ecoregion of seasonally flooded várzea forest in the central Amazon basin. It is part of the Amazon biome.
The ecoregion is home to a vegetation adapted to floods of up to 12 metres (39 ft) that may last for eight months.
There is a great variety of fish and birds, but relatively fewer mammals.
Ground-dwelling mammals must migrate to higher ground during the flood season.
Threats include logging, cattle farming, over-fishing and mercury pollution from gold mining.

A várzea forest is a seasonal floodplain forest inundated by whitewater rivers that occurs in the Amazon biome. Until the late 1970s, the definition was less clear and várzea was often used for all periodically flooded Amazonian forests.
