Lake Wobegon is a fictional town created by Garrison Keillor as the setting of the recurring segment "News from Lake Wobegon" for the radio program A Prairie Home Companion broadcast from St Paul, Minnesota. The fictional town serves as the setting for many of Keillor's stories and novels, gaining an international audience with Lake Wobegon Days in 1985. Described as a small rural town in central Minnesota, the events and adventures of the townspeople provided Keillor with a wealth of humorous and often touching stories.
