The Oregon Convention Center is a convention center in Portland, Oregon. Completed in 1989 and opened in 1990, it is located on the east side of the Willamette River in the Lloyd District neighborhood. It is best known for the twin spire towers, which provide light into the building's interior and for housing the world's largest Foucault pendulum. The center is owned by Metro, the Portland area's regional government, and operated by the Metropolitan Exposition and Recreation Commission, a subsidiary of Metro.

A convention center is a large building that is designed to hold a convention, where individuals and groups gather to promote and share common interests. Convention centers typically offer sufficient floor area to accommodate several thousand attendees. Very large venues, suitable for major trade shows, are sometimes known as exhibition halls. Convention centers typically have at least one auditorium and may also contain concert halls, lecture halls, meeting rooms, and conference rooms. Some large resort area hotels include a convention center.
