Mrs Dalloway is a novel by Virginia Woolf that details a day in the life of Clarissa Dalloway, a fictional high-society woman in post–First World War England. It is one of Woolf's best-known novels.

Created from two short stories, "Mrs Dalloway in Bond Street" and the unfinished "The Prime Minister," the novel addresses Clarissa's preparations for a party she will host that evening. With an interior perspective, the story travels forwards and back in time and in and out of the characters' minds to construct an image of Clarissa's life and of the inter-war social structure. In October 2005, Mrs Dalloway was included on Time's list of the 100 best English-language novels written since 1923.
