Biota! was a proposed aquarium in the Silvertown Quays redevelopment, on the site of Millennium Mills adjacent to the Royal Victoria Dock. It formed part of the wider Thames Gateway regeneration project for East London. Biota! would have formed one of the main public attractions in the 60-acre (24 ha), £1.5 billion development, along with Silvertown Venture Xtreme an extreme sports and surf centre.

Biota! was to be operated by the Zoological Society of London and would have been the world's first aquarium entirely based on the principles of conservation. The design for the aquarium incorporated four biomes, each representing an entire ecosystem. The £80 million aquarium building designed by Farrells was given outline planning permission in March 2005 and was initially expected to be completed in 2008, but the project was cancelled in 2009.
