|Location:||Grass Lands, Land of Ooo|
|First Appearance:||BMO Noire|
Lorraine is a chicken who appears in "BMO Noire." BMO questions her about Finn's missing sock. She lives in a small structure on one of the branches of the Tree Fort, although Finn and Jake did not know her name until BMO tells them at the end of the episode. In BMO's fantasy, she was in a relationship with BMO in the past and was seeing both Ronnie and Bebe until they died.
Lorraine looks like a regular chicken, but she has messily-applied lipstick on.
