Rio Bueno is a settlement in Jamaica. It has a population of 1,096 as of 2009. Rio Bueno, is a small seaside village on the border between the parishes of St Ann and Trelawny, and owes its importance, history and livelihood to the Rio Bueno Harbour, which is the deepest harbour in Jamaica, and perhaps one of the reasons why Columbus dropped anchor there on his first visit to Jamaica. The village sprung up during the early days of English Colonialism as a way stop for both maritime and overland visitors, and it traditionally housed taverns, guesthouses and inns. It used the postmark A70 when the post office opened in 1859. By the late 19th century the town was almost deserted, a shadow of its former self, but was then resurrected by the construction of a bauxite-shipping wharf in the mid-20th century. The village remains a picturesque gem steeped in history, with its old fort, warehouses and churches set against the water's edge with the green hills of Trelawny as its backdrop.
