Shelbyville is a fictional city on the Fox television series The Simpsons that is located adjacent to Springfield. Shelbyville and Springfield are treated in the series as twin cities, though with an intense rivalry between each other. According to Abraham Simpson, Shelbyville was also called Morganville in the past.

The City

The city of Shelbyville was founded by Shelbyville Manhattan in 1796, who held the belief that people should be allowed to marry their cousins, a practice disallowed by fellow explorer and founder of Springfield, Jebediah Springfield. As a result of this disagreement, the two founders and their party split into separate groups, and went their own ways; since that time, the populaces of Springfield and Shelbyville have held a strong rivalry. This feud was demonstrated in the episode “Lemon of Troy” when a group of Shelbyville kids stole the Springfield lemon tree.

The people of Shelbyville are apparently not much smarter or less quick to anger than the people of Springfield; as noted in one episode, the people of Shelbyville once spiked Springfield's water supply as vengeance for the people of Springfield having burned down Shelbyville's city hall, as part of (in Lisa Simpson's words) "another chapter in the pointless rivalry between Springfield and Shelbyville."

Features of Shelbyville include: its own nuclear power plant, owned by Aristotle Amadopolis; Shelbyville Elementary School; Shelbyville High School (which competes against Springfield High School in student debate competitions); a "Speed-E-Mart" convenience store; local bar "Joe's Tavern;" and yellow-colored fire hydrants. Oddly enough, most of these features, and the people staffing them, strongly resemble Springfield's (a female version of Groundskeeper Willie works at Shelbyville Elementary, for instance).

Other features include at least one mini-mall , a Best Western hotel, a city dump, and natural landmarks "Rolling Rock" (a giant boulder rolling between two steep cliffs) and Shelbyville Falls, a waterfall.

Shelbyville's sports teams include the Shelbyville Shelbyvillians, a minor league baseball team, and the Shelbyville Sharks, a football team. Once a year, the annual "Pigskin Classic" football game is held each year between the Shelbyville Sharks and Springfield's football team, the Springfield Atoms.

Shelbyville has at least one suburb, Shelbyville Heights.

Milhouse Van Houten's mother was born in Shelbyville.

Location

Like Springfield, Shelbyville is also a city located in a fictional/nonexistent U.S. state; the only things certain are that Springfield and Shelbyville are twin cities, share at least one common roadway between the two, and that Springfield's various broadcast media, particularly radio station KBBL, serves both cities. Springfield is seemingly the more dominant of the two cities, though.
