Smallville is the name of a small rural town located in Kansas which is home to the Kent family. It is also the town in which Clark Kent grew up.

Smallville is the setting for the Silver Age Superboy comics, as well as the current television series Smallville.

The town first appeared as "Smallville, USA" in Superboy (volume 1) #2 (1949). "Smallville, USA" is also a generic term to describe a relatively small American town.
