"Invasion of the Bane" is the first episode of the British science fiction television series The Sarah Jane Adventures. It was originally broadcast on 1 January 2007. Since the series was commissioned before the script for the episode was written, it is not a pilot, but a bank holiday special, and serves the introductory functions of a pilot.

The episode focuses upon a thirteen-year-old girl, Maria Jackson, discovering the existence of aliens. After discovering that the Bane, creators of a soft drink called Bubble Shock!, harbour a destructive secret, she teams up with investigative journalist Sarah Jane Smith to prevent their plans.

A thirteen-year-old girl, Maria Jackson (Yasmin Paige), and her recently divorced father Alan (Joseph Millson) move into a house opposite journalist and former time-traveller Sarah Jane Smith (Elisabeth Sladen). The night after they have moved in, Maria is woken by an ethereal light emanating from Sarah Jane's house, which she discovers, to her horrified fascination, to be Sarah Jane conversing with a star poet, or arcateenian.

The next morning, a neighbour Kelsey Hooper (Porsha Lawrence Mavour) visits and welcomes Maria before inviting her into town, using the free "Bubble Shock!" bus to travel there and tour the factory. Once they arrive at the factory, they are led to a security scanner, which surreptitiously collects their DNA to transfer to an "Archetype" (Thomas Knight) under the supervision of the factory's owner, Mrs Wormwood (Samantha Bond).
