Jupiter Reef or Jupiter Breakers is a supposed reef in the South Pacific (south of French Tuamotu islands and east of New Zealand); it appears to be a phantom reef.
Mr. Kinge, commanding the German barque Jupiter on a voyage between Newcastle, New South Wales and Tahiti, reported having passed breakers during the night of December 3rd, 1878, in . The breakers were observed in two places, each of which had a diameter of about 30 yards, and appeared to be a quarter of a mile apart. No further intelligence has been obtained regarding this shoal.[1]
Other nearby historically reported reefs which appear not to exist include Maria Theresa Reef, Ernest Legouve Reef, and Wachusett Reef.
