Two activists from the Extinction Rebellion group climbed onto a glass awning above the entrance of the embassy, and two others glued themselves to the windows.
Red handprints and streaks of red paint could be seen all over the facade, as well as slogans such as “No More Indigenous Blood” and “For The Wild”.
Extinction Rebellion, which caused widespread disruption in central London for several weeks earlier this year, said the protest aimed to challenge the Brazilian government over “state-sanctioned human rights abuses and ecocide”.
The group said the protest was timed to coincide with a march by indigenous women in Brasilia on Tuesday, and that similar actions were taking place at Brazilian embassies in Chile, Portugal, France, Switzerland and Spain.
The Brazilian embassy in London could not immediately be reached for comment.
