The Port of Seattle’s seaport is one of the most diverse in the United States. It is home to a wide range of maritime activities that brings trade to the region and generates thousands of jobs.
The Seaport is made up of 1,543 acres of waterfront land and nearby properties including container terminals, general purpose/cargo terminals, foreign trade zone, break-bulk cargo and refrigerated cargo and storage.


  • Naturally deep water port
  • 500+ acres of terminal facilities
  • 8,000 ft of moorage

  • Efficient intermodal infrastructure
  • 17 ocean carriers with direct service to Asia, Europe, Latin America, and domestic markets (Alaska and Hawaii)
