The following is a list of cities that have current tram/streetcar (including heritage trams/heritage streetcars), or light rail systems as part of their regular public transit systems. In other words, this list only includes systems which operate year-round and provide actual transit service, not ones that are primarily tourist services, are seasonal-only, or are excursion-type tram operations. Only currently operational tram and LRT systems are included in this listing – tram and LRT systems that have "suspended operation" or are presently under construction are excluded.
