The Seeker (also known as The Seeker: The Dark Is Rising) is a 2007 American family drama-fantasy film, a very loose film adaptation of the children's fantasy novel The Dark Is Rising (1973) by Susan Cooper. The film is directed by David L. Cunningham and stars Ian McShane, Alexander Ludwig, Frances Conroy, Gregory Smith, and Christopher Eccleston as the Rider. The film centers on Will Stanton (Ludwig), when on his 14th birthday, he finds out that he is the last of a group of warriors – The Light – who have spent their lives fighting against evil – The Dark. Will travels through time to track down the signs that will enable him to confront the evil forces. The Dark is personified by The Rider (Eccleston).

Released on October 5, 2007 by 20th Century Fox under a then-new joint-venture partnership known as "Fox-Walden", the film performed poorly at the box office and was panned by critics, fans of the book series, and even Susan Cooper herself for its disregard of the source material.
