Erica Steele (also known as Erica McKay) is a recurring character on FOX teen drama Beverly Hills, 90210. She is portrayed by Noley Thornton.
Erica is the daughter of Jack McKay and the younger sibling of Dylan. She was introduced in the fourth season along with her mother Suzanne, who'd come to Dylan to inform him that his father had another child. Unbeknownst to both siblings, Suzanne and her boyfriend, Kevin, were setting up a plan to steal Dylan's money. After succeeding with their embezzlement, Kevin and Suzanne took Erica and fled the country to Brazil. In the fifth season, however, Dylan, Valerie Malone, and J. Jay Jones tracked the family down in Punta Brava, Mexico, retrieved the money and took custody of Erica after Kevin and Suzanne were arrested. Erica then lived with Dylan's mother for a time in Hawaii.
It was revealed in the eighth season that Erica had returned to Beverly Hills on her own following Dylan's departure and became a prostitute working for a pimp named Riggs. By this point, she'd gained a much tougher personality. Brandon Walsh and Kelly Taylor spotted Erica on the street, and eventually succeeded in bringing her to their home for safety. After going to the authorities, they discovered that the primary issue was separating her from Riggs.
The police were later able to arrest him and create the illusion that Erica was being arrested along with him, concealing the fact that she'd set him up. Custody of Erica was then transferred by Iris to Dylan once again. Erica soon departed to live with him, remaining under his indirect care for a time after he himself returned to Beverly Hills, ensuring that she'd had a safer and better future. In the tenth season it was revealed that Dylan and Erica's father Jack was alive and living in Witness Protection under the alias Eddie Waitkus. As Eddie, Jack had a new wife named Lisa and had a son with her named Jack.
