Delta Park, Urban park in North Portland, United States

Delta Park is an urban park in north Portland, Oregon, with sports fields for softball and soccer, volleyball courts, playgrounds, and paved pathways. The eastern section holds the Owens Sports Complex, which serves both recreational players and competitive teams.

West Delta Park occupies the site of Vanport, a city built during World War II by Henry Kaiser to house shipyard workers; at its peak it was the second-largest city in Oregon, with schools, libraries and a theater. The 1948 Columbia River flood destroyed Vanport, and in the 1950s part of the area was turned into Delta Park. Signs around Force Lake describe the wildlife and explain the history of Vanport.

The park has plenty of parking and is easy to reach by car. Sports fields tend to fill up on weekends and during warmer months, so a weekday visit is generally quieter.

A section of the park contains an arboretum where tree species suited to Portland's urban climate are grown and studied. The city uses this collection as a living reference to help decide which trees to plant in other neighborhoods.
