Matilda Ziegler is an English actress, best known for her roles as Donna Ludlow in EastEnders, Irma Gobb in Mr. Bean, and Pearl Pratt in Lark Rise to Candleford.

Ziegler's first screen role was in her early twenties, during 1987–89; she appeared in the BBC One soap opera EastEnders, playing Donna Ludlow, the illegitimate daughter of series regular Kathy Beale.
