The sophomore run of the Ryan Murphy series will go by the name 'Asylum', in reference to its mental institution setting and the season's theme of "sanity and... real-life horrors".
"We picked 'Asylum' because it not only describes the setting - an insane asylum run by Jessica Lange's character which was formerly a tuberculosis ward - but also signifies a place of haven for the unloved and the unwanted," Murphy said in a statement.
"This year's theme is about sanity and tackling real-life horrors."
Franka Potente was named as the latest addition to American Horror Story's bumper cast this weekend.
The likes of Adam Levine, Chloe Sevigny, Zachary Quinto, Joseph Fiennes and Mark Consuelos have previously been confirmed for the show.
American Horror Story returns to FX in the US and UK this autumn.
