Barberism is a chain of barber shops in the Saint Mark's and Red Light District areas of Portland Island, Liberty City in 1998, the setting of Grand Theft Auto: Liberty City Stories. It is inaccessible to the player and plays no role in the storyline whatsover. All four stores are located next to Dry Cleaning businesses.
- The name of the store is a play on words of "barbarism", an act of extreme brutality and cruelty.
- By 2001, all stores are replaced with the Classic Nails business.
