"For Whom the Bell Tolls" is the 5th episode of the 5th season of the American supernatural drama television series The Vampire Diaries. It originally aired on The CW on October 31, 2013. The episode's title is a direct reference to Ernest Hemingway's novel of the same name, a common practice within The Vampire Diaries series, which frequently borrows titles from literary works.

As the veil to the Other Side weakens, the ghost population increases, causing significant problems for the living residents of Mystic Falls. Specifically, the episode sees the characters dealing with the increasing power of the spirits and attempting to maintain order as the ghostly realm encroaches on the physical world. Significant plot points involve efforts to anchor Bonnie to Jeremy, the only one who can see and interact with her, and the repercussions of Silas's plan.
