Glitch City (known in Japan rarely as バグった町, Bug Town or Bug City) or glitch location is a generic term used to describe an 'area' which is a glitchy mess of tiles, often generated using an existing location.

It is not to be confused with an unused map (although some unused maps may appear to be glitchy and/or incomplete).

One of the most well-known types of Glitch City is a wrong warp Glitch City caused by the Safari Zone exit glitch.

"Glitch City" does not refer to when the game's colors are altered among other minor things. Instead, this is often referred to as a Glitch Dimension. Some glitched areas in Pokémon Red, Blue, and Yellow may be named after what area was altered to create it. Examples of this are "Glitch League", accessed by taking the 500th step at the Pokémon League, and "Glitch Mountain", accessed by taking the 500th step on Cycling Road.

  • Glitch City RAM manipulation: When a Glitch City's block source pointer is in a location in RAM, it allows for the player to set up a specific Glitch City from buffer overflow techniques that use the screen data or cut a tree to modify a specific address in RAM to a value based on the original 4x4 map block.
  • Mystery Zone
  • Out of bounds
