Radio New Zealand (Māori: Te Reo Irirangi o Aotearoa), commonly known as Radio NZ or simply RNZ, is a New Zealand public-service radio broadcaster and Crown entity that was established under the Radio New Zealand Act 1995. It operates a news and current-affairs network, RNZ National, and a classical-music and jazz network, RNZ Concert, with full government funding from NZ on Air. Since 2014, the organisation's focus has been to transform RNZ from a radio broadcaster to a multimedia outlet, increasing its production of digital content in audio, video, and written forms.

The organisation plays a central role in New Zealand public broadcasting. The New Zealand Parliament fully funds its AM network, used in part for the broadcast of parliamentary proceedings. RNZ has a statutory role under the Civil Defence Emergency Management Act 2002 to act as a "lifeline utility" in emergency situations. It is also responsible for an international service (known as RNZ Pacific); this is broadcast to the South Pacific in both English and Pacific languages through its Pacific shortwave service.
