Felker City was a city on the planet Acamar. This city of the Vackrinos District was located in proximity to the outpost Tezber.
In 2313, after successfully raiding the outpost, the Gatherer leader Penthor-Mul holed up in this city. The Acamarian Internal Security became aware of his presence, and had him arrested on charges of terrorism, inciting to riot, and engaging in a blood feud. (TNG: "The Vengeance Factor")
This city was mentioned in the police records of Penthor-Mul, which were accessible to the crew of the USS Enterprise-D via the Acamarian planetary database.
