Cades Bay is a locality situated in Saint Mary, Antigua and Barbuda, positioned between Urlings and Old Road. It is located within the volcanic suite of Antigua and the Pineapple Belt, which is the specific region where the Antigua black pineapple can be cultivated.
The area is primarily used for crop farming and features wetlands, mangroves, and forests. A notable landmark in the community is the Cades Bay Agricultural Station on Old Road, which produces tens of thousands of Antigua black pineapples annually. The locality also hosts an annual event known as the Piango Fest.
The shores of Cades Bay are home to the Cades Bay Marine Reserve, which encompasses much of the ocean in Antigua's southwest and includes the Cades Reef. This reef is a significant site for snorkelers and plays an important role in the local economy. The region is noted to be prone to storm surges and flooding.
