is the woman who plays spencers mother on pretty little liars related to the woman who plays olivia benson on law & order special victims unit?

No, although they resemble each other, Mariska Hargitay, who plays Olivia Benson on Law & Order: SVU, is not related to Lesley Fera, who plays Spencer's mom Veronica on Pretty Little Liars. Mariska does have famous parents, as she is the daughter of Mickey Hargitay and Jayne Mansfield. She was also in the car, along with her brothers Mickey, Jr and Zoltan, when her mother was killed in a car accident.
