About Sioux City Convention Center

Welcome to the Sioux City Convention Center, a versatile event venue in the heart of Sioux City, Iowa. With about 56,000 square feet of total event space and a theater-style capacity of up to 2,800, this center is built to host weddings, conferences, tradeshows, and large gatherings. The facility features Gallery A, Gallery B, Gallery C, eight meeting rooms, Exhibit Halls, and the Grand Ballroom to accommodate events of every scale.

Located at 801 4th Street, Sioux City, IA 51101, the convention center offers convenient on-site parking and easy access to local transportation. Whether you’re coordinating a multi-day conference or a single-day expo, we’ve got you covered with practical details, trusted partner recommendations, and a straightforward booking process.

Nearby hotels provide convenient lodging for attendees, with more than 500 hotel rooms within a two-mile radius. A Courtyard by Marriott Sioux City Downtown/Convention Center block of 150 rooms is attached to the area, making travel simple for guests. For easy commuting from the hotel to the venue, Sioux City Transit serves the downtown area via the Martin Luther King Jr. Transportation Center.

The convention center hosts 200+ events per year and continues to be a premier destination for gatherings in Sioux City. Note: The nearby Siouxland Expo Center was renamed Seaboard Triumph Foods Expo Center—this change is separate from the Sioux City Convention Center itself.
