The Tomorrow series is a series of seven young adult invasion novels written by Australian writer John Marsden, detailing the invasion and occupation of Australia by a foreign power. The novels are related from the first-person perspective by Ellie Linton, a teenage girl, who is part of a small band of teenagers waging a guerrilla war on the enemy soldiers in the region around their fictional home town of Wirrawee. The name of the series is derived from the title of the first book, Tomorrow, When the War Began.

Invasion literature is a literary genre that was popular in the period between 1871 and the First World War (1914–1918). The invasion novel was first recognised as a literary genre in the UK, with the novella The Battle of Dorking: Reminiscences of a Volunteer (1871), an account of a German invasion of England, which, in the Western world, aroused the national imaginations and anxieties about hypothetical invasions by foreign powers; by 1914 the genre of invasion literature comprised more than 400 novels and stories.
The Battle of Dorking (1871) established the genre of invasion literature. (Cover of the 1914 edition)
