Most of Wikipedia's articles about indoor arenas in the United States have also been allocated to one or more of the categories for individual sports, but they should also be left in the appropriate "indoor arenas by state" subcategory of this category as most indoor arenas also stage other events such as concerts or conventions, or occasional events in sports which do not provide their regular tenants, e.g. tennis, gymnastics, boxing or rodeo. However it is not necessary to categorise the individual arenas as music venues or concert halls because this category is a subcategory of category:music venues in the United States.

Some of the subcategories contain a few Canadian arenas.

This is a container category. Due to its scope, it should contain only subcategories.
