Petre Bay is a large bay which comprises about half of the west coast of Chatham Island, the largest island in New Zealand's Chatham Islands archipelago. It is some {{Convert|20|km|mi}} in extent, and contains the far smaller Waitangi Bay, where the island group's largest settlement, Waitangi is located.

The bay is named after Lord Petre, a director of the New Zealand Company.{{citation|title=Petre Bay|language=en|work=New Zealand Gazetteer|author=New Zealand Geographic Board|publisher=Land Information New Zealand|access-date=2024-02-07|url=https://gazetteer.linz.govt.nz/place/13959|archive-url=http://web.archive.org/web/20230712221500/https://gazetteer.linz.govt.nz/place/13959|archive-date=2023-07-12}}
