Rotokura/ Cable Bay is a bay and small settlement 18 kilometres north-east of Nelson in New Zealand. The settlement at the head of the bay is at the southern end of a thin strip of land or causeway connecting Pepin Island with the South Island. The New Zealand Ministry for Culture and Heritage gives a translation of "red glow of sunset on the water" for Rotokura. The bay itself is a 600 metres wide, northwest-facing bay in the Tasman Bay/ Te Tai-o-Aorere.
