Totaranui Beach, Beach destination in Abel Tasman National Park, New Zealand

Tōtaranui Beach is a 1 km long beach in Abel Tasman National Park, at the northern end of the Abel Tasman Track. Its sand is notably golden, more intense than other beaches in the park, due to a high content of orthoclase minerals in the eroded granite sands of the vicinity. The beach is the site of a large campsite administered by the Department of Conservation.

Ngāti Tūmatakōkiri, displaced from Queen Charlotte Sound / Tōtaranui by Ngāti Kurī, settled the coast north of the sounds and may have brought the name Tōtaranui with them. The bay later became a farming settlement; farming ceased after Abel Tasman National Park was founded in 1942, and forest has since regenerated through mānuka and kānuka toward southern beech and lowland podocarp.

The Ministry for Culture and Heritage translates Tōtaranui as "many tōtara trees". The name may have travelled with the Ngāti Tūmatakōkiri, who were forced out of Queen Charlotte Sound / Tōtaranui by Ngāti Kurī and settled along the coast north of the sounds, possibly bringing the name with them.

Tōtaranui is reached by road from Tākaka over Pigeon Saddle, or by water taxi from Mārahau. The beach lies at the northern end of the Abel Tasman Track, so it works as a start or finish for the walk. The large campsite is run by the Department of Conservation; in summer it holds up to 1000 campers plus hikers.

The beach serves as the starting point for the famous Abel Tasman Track, a multi-day walking route that crosses the entire park coastline. During summer season the population swells as thousands of hikers and campers use the trail or stay along the shore.
