To the Lighthouse is a novel by Virginia Woolf. The novel centres on the Ramsay family and their visits to the Isle of Skye in Scotland between 1910 and 1920.

To the Lighthouse, considered by many to be Virginia Woolf's finest novel, is a remarkably original work, showing the thoughts and actions of the members of a family and their guests on two separate occasions, ten years apart. The setting is Mr and Mrs Ramsay's house on a Scottish island, where they traditionally take their summer holidays, overlooking a bay with a lighthouse.

In 1998, the Modern Library named To the Lighthouse No. 15 on its list of the 100 best English-language novels of the 20th century.
