Brighton Rose Sharbino is an American actress. She is best known for her role as Lizzie Samuels on the AMC television series The Walking Dead.

Lizzie and Mika Samuels are fictional characters from the fourth and fifth season of the AMC television series The Walking Dead portrayed by Brighton Sharbino and Kyla Kenedy, based on The Walking Dead comic book characters Billy and Ben, gender-swapped in-adaptation. Introduced in the fourth season premiere, Lizzie and Mika are two young siblings, and the daughters of Ryan Samuels. Following the death of their father, Carol agrees to raise the girls as her own children. The struggles of Lizzie and Mika are contrasted within the series as Lizzie, capable of taking a human life, is unable to kill walkers, instead believing she can communicate with them and have an emotional connection. Conversely, Lizzie's younger sister, Mika, willingly kills walkers, but her compassion for others prevents her from taking the life of another human being.
