Activists are to target the headquarters of RBS to highlight deals which they say contribute to climate change.
The Camp for Climate Action intend to set up a camp by "swooping" on a site in or near Edinburgh from 19 August.
Protesters are expected to target the bank on 23 August.
The campaign group said it had chosen RBS because of its commitment to financing the fossil fuel industry in the UK and around the world.
This includes loans to coal, oil and gas companies.
The activists pointed out that previous camps had successfully targeted the now axed third runway at Heathrow and Kingsnorth power station in Kent.
Ruth Brown, a community worker from London, said: "Destructive projects like open-cast coal mines in the UK are only made possible through finance from banks like RBS.
"The government bailed them out, and now they use their profits to destroy our communities and are causing catastrophic climate change."
