The Port of Portland (Port Code:USPDX) is the port district responsible for overseeing Portland International Airport, general aviation, and marine activities in the Portland, Oregon metropolitan area in the United States. Originally established in 1891 by the 16th Oregon Legislative Assembly, the current incarnation was created by the 1970 legislature, combining the original Port with the Portland Commission of Public Docks, a city agency dating from 1910.

The Port manages five industrial parks around the metropolitan area, and they own and operate the Dredge Oregon to help maintain the navigation channel on the lower Columbia and Willamette rivers
