丰盛湾，也称作普伦蒂湾（英文：Bay of Plenty），新西兰北岛海湾，普伦蒂湾大区即以此海湾命名。丰盛湾从科罗曼多半岛一直延伸至动部的Cape Runaway。丰盛湾由库克船长于1769年航行至此时命名，库克船长当时意识到了这个地区的食物供给充足，而且他访问的几个毛利部落中，景况比他命名的贫穷湾（Poverty Bay）中见到的大不一样。

The Bay of Plenty, known in Māori as Te Moana-a-Toi, is a large indentation in the northern coast of New Zealand's North Island. It stretches from the Coromandel Peninsula in the west to Cape Runaway in the east, a wide stretch of some 259 km of open coastline. The Bay of Plenty Region is situated around this body of water, also incorporating several large islands in the bay.
