Tinline Campsite sits within Abel Tasman National Park in New Zealand's Nelson/Tasman region, roughly 3 kilometres from the park's southern entrance at Mārahau.

It lies just 300 metres down the Abel Tasman Coast Track from the Inland Track junction, making it one of the most accessible campsites in the park. The campsite occupies a gently sloping grassy area with capacity for around 30 people across 15 sites.

Unlike most Abel Tasman campsites, it is not positioned directly on the beach, but the short approach offers pleasant views. A small nature walk runs through the area, where the Abel Tasman Birdsong Trust has carried out extensive replanting of native trees.

The site is managed by the Department of Conservation and is particularly well suited to families with young children given its easy access from the trailhead.
