Expo Center is a light rail station on the MAX Yellow Line in Portland, Oregon, United States. It is the last stop northbound on the Interstate MAX extension.

This station is a large park-and-ride station located on the grounds of the Portland Expo Center. It is set up as a modified side platform station, with the two platforms serving three tracks. The extra track allows the storage of an overflow train for events at the Expo Center. 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.

Both the landscaping and the artwork at the station are themed in a Japanese style. 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.

This station is at the Expo Center served by the following bus line:

• 11 - Rivergate/Marine Dr
