Meredith Blake is the main antagonist of the 1998 remake of "The Parent Trap". She is a 26-year-old gold-digger who plans on marrying Nick Parker, the divorced father of the twin protagonists, Hallie and Annie, for money, and to send "Hallie" (who she doesn't know is really Annie switching places) to a boarding school.

Near the end, when on a camping trip instead of the twins' real mother Elizabeth James, the twins play pranks on her, until eventually, when they have shipped her mattress out into the lake, she falls off when she sees a bird land on her and when she sees where she is. She yells at Nick, telling him that as soon as they marry, they'll send the girls off to Switzerland, and demands he chooses between her and them. He picks the twins and makes it clear, much to her dismay. In fact, she throws a tantrum at him and calls off the engagement.

Elaine Hendrix portrayed her.
