Expo Center is a light rail station on the MAX Yellow Line in Portland, Oregon, United States.

The 300 park-and-ride spaces are free for commuters arriving before 10 am on weekdays for a maximum 24 hours.

At all other times, drivers must pay the Expo Center's usual $7–8 parking fee.

Although tracks and electrification end directly inside the station, it is designed to allow a future northbound extension (to Vancouver, Washington) to be easily constructed.

This recalls the temporary Civilian Assembly Center that existed here during the early days of World War II, which processed Japanese-Americans upon the enforcement of Executive Order 9066.
