Big South Cape Island or Taukihepa is an offshore island of New Zealand to the west of the southern tip of Stewart Island / Rakiura. The island has no permanent inhabitants but muttonbirders visit the island to catch the sooty shearwater, known in New Zealand as a "muttonbird". Māori named the island "Taukihepa" and Europeans, who arrived later, called it "Big South Cape". The island was given dual names in 2001 as part of a Treaty of Waitangi settlement with Ngai Tahu.
