Radiant City is a 2006 Canadian film written and directed by Gary Burns and Jim Brown. It is about the suburban sprawl and the Moss family's life in the suburbs. The film is openly critical towards suburban sprawl and its negative effects, being ironic and amusing at the same time.

It was revealed to be a mockumentary at the end of the film.

The fictional part is about the five members of the Moss family who have just moved from the city into a new suburban development of Evergreen (part of Evergreen) in Calgary, Alberta. The family discuss and portray the life in the suburbs and the various flaws and advantages of a modern suburban life, with a considerably greater emphasis on the flaws. While the characters and instances in the movie are fictional, the actors that play them all live in real suburban areas.

Interspersed with this narrative, experts speak about their views of the suburbs. These include Ken Greenberg, Joseph Heath, Mark Kingwell, James Howard Kunstler, Marc Boutin, Andrés Duany and Beverly Sandalack. These portions are filmed in different suburban areas of North America, including Oakville, Ontario.
