The addition of the Carter children, Johnny and Nancy, has also been confirmed, with Sam Strike and Maddy Hill joining the cast of the BBC soap.
Parents Mick (Danny Dyer) and Linda (Kellie Bright) will arrive in Albert Square later this year to take over the Queen Vic.
Speaking about his casting, Strike said: ''I'm really excited to be joining EastEnders and the Carter family. They're all really strong characters and I can't wait to see what EastEnders has planned for us all.
"I've grown up watching Danny and Kellie, both of whom are lovely, so to be playing their son is kind of surreal."
Hill added: "I feel incredibly privileged to have been given such an amazing opportunity and I can't wait to start work with such a talented cohort of actors."
The family will join Shirley (Linda Henry) and Tina (Luisa Bradshaw-White) in Walford. Bradshaw-White will make her first appearance as Tina next month.
Dominic Treadwell-Collins, executive producer on the serial drama, said: "My team have worked incredibly hard over the past few months to create the Carters - a contemporary British family with cracks, knocked edges and a touch of darkness that is going to make them very special to watch.
"A family of strong characters who love and hate each other, all rooted in the best traditions of EastEnders," he teased.
