Suspense is a 1913 American silent short film thriller directed by Lois Weber and Phillips Smalley. Weber also wrote the scenario and stars in the film with Valentine Paul. The film features early examples of a split screen shot and a car chase. The Internet Movie Database lists Lon Chaney as having an unconfirmed and uncredited brief role; however, this is disputed by silentera.com, which states "Despite attributions to the contrary, Lon Chaney does not appear in the film."A print of the film is preserved at the film archive of the British Film Institute.

In 2020, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
