Impact Arena, Exhibition and Convention Center, Muang Thong Thani (Thai: ศูนย์แสดงสินค้าและการประชุม อิมแพ็ค เมืองทองธานี) is a commercial complex consisting of an arena, convention centre and exhibition halls, located in Muang Thong Thani in Pak Kret District of Nonthaburi Province, a northern suburb of Bangkok, Thailand.

It has been considered as the second largest exhibition and convention venue in Asia with an indoor floor space of over 140,000 sqm.

Bangkok Land had been selected as a venue for the games before the crisis, and there were concerns whether it would be able to finish the construction on time.

[2][3] The Muang Thong Thani Sports Complex hosted boxing, weightlifting, billiards & snooker, gymnastics, volleyball, tennis and rugby competitions.

The weightlifting and rugby venues, now Thunder Dome and Thunderdome Stadium, had their ownership contractually transferred to the Sports Authority of Thailand.
