Basket Swamp National Park, Nature reserve in Tenterfield Shire Council, Australia.

Basket Swamp National Park lies 15 km north-east of Tenterfield in north-eastern New South Wales. Most of the park is a swamp whose soils are rich in organic material, and its trees carry a yellow colour that comes from old sulphur deposits. The central swamp is ringed by shrubs whose branches formed a woven basket-like fabric, the source of the park's name.

In 1998 Marshall Martin found a sea-level area that had been cut off from other regions for thousands of years, where diverse endemic fish species had developed. In a deeper soil layer, labelled layer 27, artefacts between 10,000 and 15,000 years old were found. The park takes its name from the central swamp surrounded by shrubs whose branches formed a woven fabric.

The park's name comes from Basket Swamp, the shrub-ringed wetland at its centre; the German source records that the branches of these shrubs formed a woven fabric, a basket. The swamp itself is the feature that gives the place its identity, holding organic-rich soils and feeding streams of the Clarence River catchment.

Visitors need a four-wheel drive vehicle to navigate the unsealed roads and reach the park. Plan ahead, as access conditions can be rough and weather-dependent.

Basket Swamp, the waterlogged area in the park's western sector that gives the park its name, cleans, stores and discharges water into streams feeding the Clarence River. German sources add that the swamp is ringed by shrubs whose branches formed a woven fabric, and that Marshall Martin found a landlocked marine plain there in 1998.
