baseball parks had smaller capacities, natural grass, and a wider field, these parks were generally in use during summer, when North American–based soccer leagues, such as Major League Soccer, also hold their seasons, and the irregular field dimensions and sightlines were often considered undesirable. Soccer-specific stadiums first came into use in the 1990s, after the multi-purpose stadium era. The term "soccer-specific stadium" was coined by Lamar Hunt, who financed the construction of the Columbus Crew Stadium, the first soccer-specific stadium constructed specifically for Major League Soccer. In the 2000s, other Major League Soccer teams in the United States began constructing their own stadiums. Canada's first soccer-specific stadium was BMO Field in Toronto, home to Toronto FC.

Of the three Canadian cities that host both MLS and CFL teams, only one (Montreal) has separate stadiums for each.

The term tends to have a slightly different meaning in these countries, usually referring to a stadium without an athletics track surrounding the field. Some soccer stadiums in Europe are also used for other sports, including rugby, American
