Queen Sirikit National Convention Center

Queen Sirikit National Convention Center is Bangkok's national convention venue, set beside Queen Sirikit MRT station in Khlong Toei. After a full rebuild it reopened around 2022 with about 78,500 sqm of event space, including four plenary halls, four ballrooms, eight exhibition halls and roughly 50 flexible meeting rooms. Directory listings give the largest room a capacity of about 5,700, with the main plenary hall listed at up to 6,000 theatre-style, though published figures vary between the old and new buildings, so confirm layouts with the venue. The centre suits international association congresses, government summits and large corporate conferences that need plenary, breakout and exhibition space on one site. Ballrooms support gala dinners and awards evenings, and the MRT connection simplifies delegate transfers from city hotels.
