Jamaica's Boundary Rivers: Natural Parish Dividers

Several Jamaican rivers form natural boundaries between parishes, shaping the island's administrative geography:

Other Boundary Rivers

• Cobre River – St. Ann / St. Mary
• Yallahs River – St. Thomas / Kingston (boundary)
• Morant River – St. Thomas / Portland
• Plantain Garden River – St. Thomas (easternmost)

These rivers reflect Jamaica's radial drainage from the central mountains (Blue Mountains, John Crow Mountains) to the coast. They've defined parish lines since colonial times and remain ecological and cultural landmarks.
