The Port of San Juan (Spanish: Puerto de San Juan) is a seaport facility located in the metropolitan area of San Juan, Puerto Rico.
The "Port of San Juan" is the general name used to call various passenger and cargo facilities located in lands around the San Juan Bay (Bahía de San Juan). The port is composed of a total of sixteen piers, of which eight are used for passenger ships and eight for cargo ships. The port's facilities, in addition to, Luis Muñoz Marín International Airport and the Cataño Ferry "Lancha de Cataño" services, are property of the Puerto Rico Ports Authority.
The bay and its docks are located along San Antonio Canal, a narrow navigable section of San Juan Bay lying south of Old San Juan and San Juan island, and north and west of the Puerto Rico Convention Center District and Isla Grande Airport. The municipalities of Cataño, Guaynabo and San Juan compose the south side of the bay and port.
The Port of San Juan's cargo facilities are located on the southern portion of San Juan Bay. Of the approximately eight cargo terminals, five are located in the Puerto Nuevo district of San Juan and the other three are located in the neighboring municipality of Guaynabo. The cargo facilities allow for more than 500,000 square feet (46,000 m²) of space for loading and unloading cargo.
The location of the port's cargo facilities give it immediate access to Puerto Rico's vast expressway system and several major local routes, this allows for the fast and efficient transportation of goods throughout the Metropolitan Area and the rest of the island.
The Port of San Juan's passenger facilities are located along San Antonio Canal. Of the 15 piers in the channel, four accommodate cruise ships while others serve cargo vessels and the La lancha de Cataño (Cataño Ferry).
