Zizi, a young French girl, is a character from the British television series Supercar.

Like the Gibson brothers before her, Zizi becomes part of the secret world of a certain secluded Black Rock, Nevada laboratory quite by happenstance. In the series episode Precious Cargo, she is discovered to have stowed away (!) in a shipment of French wine sent to Professor Popkiss. His sister Heidi takes her into her own home, to look after her.

Zizi and Aunt Heidi both return, for Mike Mercury's big birthday party at the lab, in the subsequent episode The Day That Time Stood Still.

She was voiced by Sylvia Anderson.
