Nothofagus fusca, commonly known as red beech (Māori: tawhai raunui) is a species of southern beech, endemic to New Zealand, where it occurs on both the North Island and South Island. Generally it is found on lower hills and inland valley floors where soil is fertile and well drained. In New Zealand the species is called Fuscospora fusca. Pollen from the tree was found near the Antarctic Peninsula showing that it formerly grew in Antarctica since the Eocene period. Red beech is not currently considered threatened.
