Speaking at PaleyFest 2013, the series creator said that season three will be subtitled Coven.
It apparently will take place in various cities including New Orleans, and will shoot on location for the first time.
"The fun thing is researching what are the really haunted places in America, and we have a couple doozy locales," said Muprhy, who also created Glee and Nip/Tuck.
The second season of the show was subtitled Asylum, and took place inside a 1960s insane asylum.
American Horror Story: Coven will once again star Jessica Lange, who appeared in the previous two seasons. Lange will be joined by Kathy Bates, who will play a longtime friend-turned-rival of Lange's character.
The third season will also feature returning castmembers Evan Peters and Sarah Paulson.
