Mealey Eubank went missing from a foster home where she is in care of the local authority on Tuesday afternoon.
She is described as black, 5ft 7in tall, slim, with brown eyes and collar-length afro-style brown hair.
She was wearing a grey baseball-style top with black sleeves, and jeans. She took with her a bag of clothes.
Inquiries have been made among her friends and family throughout the Brighton area and farther afield but Sussex Police said that there was as yet no sign of her.
Detective Inspector Lee Horner said; “There is no evidence of any suspicious circumstances or that Mealey has come to any harm but with every day and with the current lack of information we naturally become increasingly concerned.
“If you have seen Mealey, or know here she may be please contact us via email@example.com or call us on 101.”
