Myriad Convention Center (and later Cox Convention Center) was a film production complex located in downtown Oklahoma City, Oklahoma. It was formerly a convention center and the home of several minor league teams. The convention center was replaced in January 2021 by the Oklahoma City Convention Center. The site was demolished in February 2026 to make room for a new basketball arena for the Oklahoma City Thunder. The facility, known as the Myriad Convention Center, originally was the centerpiece of Oklahoma City's first major urban renewal project, the Pei Plan. In addition to the Convention Center, the project included the removal of blighted sections of the southern downtown area. The project also began the process for the design and construction of the Myriad Botanical Gardens, located directly west of the Myriad. As the Myriad, the facility received a major renovation and expansion. The US$55.8 million project was designed by Glover Bode. Flintco, who served as the renovation's general contractor, began construction in June 1997. The work was completed in August 1999. It was later named Cox Convention Center via sponsorship with telecommunications company Cox Communications. The facility's primary use was that of large-scale convention and meeting space. It also hosted major concerts, conferences, and other large-scale events. The complex houses multiple meeting rooms, conference and convention space, dining halls, and a 15,000-seat multi-purpose arena. When it opened in 1972, it replaced the Oklahoma State Fair Arena as Oklahoma City's main indoor sports and concert venue. It would retain this status for 30 years until the opening of the Ford Center (now the Paycom Center) in 2002 directly across the street. As the Cox Convention Center, the facility received another upgrade, budgeted at $4.5 million, to accommodate the Edmonton Oilers' top farm team, the Oklahoma City Barons, which began play in the 2010-11 season. The arena was home to Oklahoma City Blazers h
