The following is a list of stadiums in Wales, in order by capacity. The list only includes stadiums and grounds that have been built and remain in use, with a capacity of at least 2,000 temporary seating included. The ground of successful Welsh club The New Saints is not included because it is in England, not Wales (Park Hall).
