Bonne Nuit (Jèrriais: Bouonne Niet) is a small natural harbour in the Vingtaine du Nord, Saint John, Jersey, Channel Islands.

Both Bonne Nuit in French and Bouonne Niet in Jèrriais mean "good night", referring to the shelter sailors could rely on by overnighting in the harbour.

The priory and chapel continued its existence, owning land at neighbouring Frémont, and being noted for the dinner the prior was obliged to offer to the Bailiff of Jersey, the Vicomte and the King's Receiver every Midsummer day.

[1] The threat of French invasion led to the building of a small fort at La Crête, overlooking both Bonne Nuit and the adjacent bay Le Havre Giffard, between 1816-1834.

According to legend, the rock is the petrified remains of a water sprite who took the form of a horse to abduct and drown a man called Guillaume in order to steal away his sweetheart Anne-Marie.
