Wersching will play Emma - first love of Miles Matheson (Billy Burke) - on the hit NBC drama, TVLine reports.
Sebastian Monroe (David Lyons) is also obsessed with Emma, leading to another confrontation between him and Miles when she resurfaces in the present day.
Wersching is the third 24 veteran to recently land a role on Revolution - Kim Raver and Leslie Hope both previously booked stints on the sci-fi drama.
Her guest role on Revolution marks the latest high-profile casting for Wersching, who has also signed up for roles on Body of Proof, Dallas and Kiefer Sutherland's new drama Touch in recent months.
Revolution will return from hiatus on March 25. The series has been on a four-month break, which creator Eric Kripke claims has helped to improve the show.
