The Port of Miami is a seaport located in Biscayne Bay in Miami, Florida, United States. It is connected to Downtown Miami by Port Boulevard, a bridge over the Intracoastal Waterway. It is located on Dodge Island.

The port is recognized as the "Cruise Capital of the World" and "Cargo Gateway of the Americas". It has retained its status as the number one cruise/passenger port in the world for well over a decade accommodating the largest cruise ships and the major cruise lines.

As the "Cargo Gateway of the Americas", the port primarily handles containerized cargo with small amounts of breakbulk, vehicles and industrial equipment. It is the largest container port in the state of Florida and ninth in the United States. As a world-class port, the Port of Miami is among an elite group of ports in the world which cater to both cruise ships and containerized cargo.

The Port of Miami is an important contributor to the local and state economies. Nearly four million cruise passengers pass through the Port and over 9 million tons of cargo and over 1 million twenty-foot equivalent units (TEU) of shipping container traffic move through the seaport per year. This combination of cruise and cargo activities supports approximately 98,000 jobs, and has an economic impact in Miami-Dade County of over $12 billion.

The port currently operates six passenger terminals, six gantry cranes wharves, seven Ro-Ro (Roll-on-Roll-off) docks, four refrigerated yards for containers, a refrigerated warehouse, break bulk cargo warehouses and twelve gantry container handling cranes. Additionally, cargo handling and support equipment are operated by port tenants who operate most of the facilities.

To retain the port's competitive rank as a world-class port, the port has undertaken a redevelopment program of over $250 million which is well underway to accommodate the changing demands of cruise vessel operators, passengers, shippers and carriers.
