The Portland Metropolitan Exposition Center, usually referred to as the Expo Center, is a convention center located in the Kenton neighborhood of Portland, Oregon, United States. Opened in the early 1920s as a livestock exhibition and auction facility, the Expo Center now hosts over 100 events a year, including green consumer shows, trade shows, conventions, meetings and other special events. Located on the north side of Portland near Vancouver, Washington, it includes the northern terminus for the Yellow Line of Portland's light-rail transit system and has connections to Trimet Bus Line 11-Rivergate/Marine Dr.

The complex was originally built in the early 1920s as the Pacific International Livestock Exposition, and operated as a livestock exhibition, cattle grading, and auction facility.“Alexander Chalmers, Centerville/Forest Grove, breeder of Shorthorn Cattle; Frank Brown, Carlton, breeder of Shropshire Sheep and Shorthorn Cattle; Herb Chandler, Baker, breeder of Hereford Cattle; A.C.

The show later had a side line of holding huge auctions of livestock for breeding purposes.

Later the show included horse show and rodeo venues.

From May 2 to September 10, 1942, the Center suspended livestock exposition operations and served as a Civilian Assembly Center under President Roosevelt's Executive Order 9066, which authorized the eviction and confinement of Japanese Americans living on the West Coast during World War II. 3,676 people of Japanese descent were confined in the hastily converted animal corrals for a period of five months, while they awaited transfer to more permanent camps in California, Idaho and Wyoming.Torii Gate, an installation piece by Portland artist Valerie Otani, acts as a memorial honoring the people held at the Portland Assembly Center in 1942.
