Lindsey is a girl whom Chris dates who looks disturbingly like his mother, Lois Griffin, in "Tom Tucker: The Man and His Dream".
Lindsey is unfaithful and promiscuous, and has multiple other boyfriends besides Chris. When Lois finds out, she tells Chris the truth, only to find that Chris already knew, and he was with Lindsey mostly because she looks a lot like Lois, and thus Chris thought she would act like Lois, in the sense that Lois puts up with Peter all the time, and Chris thought the only person who could love him would be someone like his own mother.
After Lois assures him that someday he will meet someone, Chris breaks up with Lindsey, who then starts dating Quagmire.
She is voiced by Elliot Page.
